The Cold War’s Toxic Legacy: Costly, Dangerous Cleanups at Atomic Bomb Production Sites
By William J. Kinsella
Seventy-five years ago, in March 1943, a mysterious construction project began at a remote location in eastern Washington state. Over the next two years some 50,000 workers built an industrial site occupying half the area of Rhode Island, costing more than $230 million—equivalent to $3.1 billion today. Few of those workers, and virtually no one in the surrounding community, knew the facility's purpose.
The site was called Hanford, named for a small town whose residents were displaced to make way for the project. Its mission became clear at the end of World War II. Hanford had produced plutonium for the first nuclear test in the New Mexico desert in July 1945, and for the bomb that incinerated Nagasaki on Aug. 9.
As a researcher in environmental and energy communication, I've studied the legacies of nuclear weapons production. From 2000 to 2005, I served with a citizen advisory board that provides input to state and federal officials on a massive environmental cleanup program at Hanford, now one of the most contaminated sites in the world.
As U.S. leaders consider producing new nuclear weapons, I believe they should study lessons from Hanford carefully. Hanford provides one of the more dramatic examples of problems that unfolded—and persist today—at nuclear sites where production and secrecy took priority over safety and environmental protection.
A Nationwide Nuclear Network
Hanford was one of three large facilities anchoring the Manhattan Project – the crash program to build an atomic bomb. It was part of a larger complex linking facilities across the nation. A plant at Oak Ridge, Tennessee, enriched uranium and operated a prototype nuclear reactor. Los Alamos Laboratory in New Mexico assembled a cadre of world-class scientists to design and build the weapons, using materials produced at the other sites. Smaller facilities across the nation made other contributions.
As World War II phased into the Cold War and the U.S.-Soviet arms race escalated, new sites were added in Ohio, South Carolina, Florida, Texas, Colorado and elsewhere. Secrecy masked much of the work at these sites until well into the 1980s, with serious consequences for public health, worker safety and the environment. Nuclear and chemical wastes caused severe contamination at Hanford and the other sites, and dealing with them has proved to be difficult and costly.

Contamination at Hanford
When the Soviet Union disintegrated in 1991, the U.S. had mass-produced some 70,000 nuclear bombs and warheads. Hanford made most of the plutonium used in those weapons. Workers irradiated uranium fuel in reactors, and then dissolved it in acid to extract the plutonium produced. This method, called reprocessing, generated 56 million gallons of liquid wastes laced with radioactive and chemical poisons.
Hanford's nine reactors were located along the Columbia River to provide a source of cooling water, and discharged radiation into the river throughout their lifetimes.
Fuel was sometimes reprocessed before its most highly radioactive isotopes had time to decay. Managers knowingly released toxic gases into the air, contaminating farmlands and grazing areas downwind. Some releases supported an effort to monitor Soviet nuclear progress. By tracking intentional emissions from Hanford, scientists learned better how to spot Soviet nuclear tests.
Liquid wastes from reprocessing were stored in underground tanks designed to last 25 years, assuming that a permanent disposal solution would be developed later. The U.S. Department of Energy, which now operates the weapons complex and its cleanup program, is still working on that solution.

Meanwhile, at least a million gallons of tank wastes have
leaked into the ground. This material, and the prospect of more to follow, threatens the Columbia River, a backbone of the Pacific Northwest's economy and ecology. Some groundwater is already contaminated. Estimates of when that plume will reach the river are uncertain.
Radioactive trash still litters parts of Hanford. Irradiated bodies of laboratory animals were buried there. The site houses radioactive debris ranging from medical wastes to propulsion reactors from decommissioned submarines and parts of the reactor that melted down at Three Mile Island. Some nuclear decision makers have called Hanford a "national sacrifice zone."
A Struggle for Accountability
In the mid-1980s, local residents grew suspicious about an apparent excess of illnesses and deaths in their community. Initially, strict secrecy—reinforced by the region's economic dependence on the Hanford site—made it hard for concerned citizens to get information.

Once the curtain of secrecy was partially lifted under pressure from area residents and journalists, public outrage prompted two major health effects studies that engendered fierce controversy. By the close of the decade, more than 3,500 "downwinders" had filed lawsuits related to illnesses they attributed to Hanford. A judge finally dismissed the case in 2016 after limited compensation to a handful of plaintiffs, leaving a bitter legacy of legal disputes and personal anguish.
Cleanup operations at Hanford began in 1989, but have been hamstrung by daunting technical challenges and management errors. The current estimate assumes work will continue through 2060 and cost more than $100 billion, beyond the approximately $50 billion already spent.
A key challenge is building a facility to extract the most toxic materials from the tank wastes and enclose them in glass logs to be sent elsewhere for permanent burial. Projected costs have ballooned to more than $17 billion, and the estimated completion date is now 2036. And with the proposed Yucca Mountain nuclear waste repository in Nevada mired in controversy, there is still no final resting place for these materials, which will be dangerous for tens of thousands of years.
Cleanup has progressed in other areas. The reactors have been shut down and enclosed in concrete and steel "cocoons" until their radioactivity decays further. Hanford's "B Reactor," the world's first large-scale nuclear reactor, is now part of the Manhattan Project National Historic Park.
Buffer lands around the outer parts of the site, presumably clean enough for the purpose, have been converted to wildlife refuge areas. And in 2015, the Laser Interferometer Gravitational Observatory (LIGO), with a station located at Hanford, detected the first gravitational waves predicted by Albert Einstein. LIGO scientists chose Hanford for its remote location and minimal interference from human activity.
Lessons to Remember
The Department of Energy now considers many of its former nuclear weapons production sites to be fully cleaned up. Some remaining sites are involved in maintaining the current nuclear arsenal and could play roles producing new weapons. Others, like Hanford, are "legacy" sites where cleanup is the sole mission.
There is more oversight of the nuclear weapons complex today, but serious concerns remain. Notably, inspectors have found problems at Los Alamos National Laboratory dating back to 2011 related to handling of beryllium, a toxic material that can cause cancer and lung disease.
These issues at Hanford and other nuclear sites are reminders that nuclear weapons production is a risky process—and that in Washington state and elsewhere, legacies of the Cold War are still very much with us.

Since even moderate-intensity workouts offer a slew of benefits, walking is a good choice for people looking to stay healthy.
How to Rock Your Walk<p>Walking isn't just fun and healthy. It's accessible.</p><p>"Walking is cheap," says Dr. John Paul H. Rue, a sports medicine doctor at <a href="https://mdmercy.com/" target="_blank">Mercy Medical Center in Baltimore</a>. "You can do it anywhere at any time; [it] requires little to no special equipment and has many of the same cardio benefits as running or other more intense workouts."</p><p>Want to up your walking game? Try the tips below.</p>
Use Hand Weights<p>Cardio and strength training can go hand-in-hand when you add weights to your walk.</p><p>A <a href="https://journals.lww.com/acsm-msse/Fulltext/2019/03000/Associations_of_Resistance_Exercise_with.14.aspx" target="_blank">2019 study</a> found that weight training is good for your heart, and <a href="https://www.mayoclinicproceedings.org/article/S0025-6196(17)30167-2/abstract" target="_blank">research</a> shows it reduces the risk of developing a <a href="https://www.healthline.com/health/nutrition-metabolism-disorders" target="_blank">metabolic disorder</a> by 17 percent. People with metabolic disorders have a higher chance of being diagnosed with high cholesterol, high blood pressure, and diabetes.</p><p>Rue suggests not carrying weights for your entire walk.</p><p>"Hand weights can give you an added level of energy burning, but you have to be careful with these because carrying [them] over a long period of time or while walking could actually lead to some overuse injuries," he says.</p>
Make It a Circuit<p>As another option, consider doing a circuit. First, put a pair of dumbbells on your lawn or somewhere in your home. Walk around the block once, then stop and do some bicep curls and tricep lifts before walking around the block again.</p><p>Rue recommends <a href="https://www.healthline.com/health/exercise-fitness/running-with-weights" target="_blank">avoiding ankle weights</a> during cardio workouts, as they force you to use your quadriceps rather than hamstrings. They can also cause muscle imbalance, according to the <a href="https://www.health.harvard.edu/staying-healthy/wearable-weights-how-they-can-help-or-hurt" target="_blank">Harvard Health Letter</a>.</p>
Find a Fitness Trail<p>Strength training isn't limited to weights. You can get stronger by <a href="https://www.healthline.com/health/bodyweight-workout" target="_blank">simply using your body</a>.</p><p>Often found at parks, fitness trails are obstacle courses with equipment for pullups, pushups, rowing, and stretches to build upper and lower body strength.</p><p>Try searching "fitness trails near me" online, checking out your local parks and recreation website, or calling the municipal office to <a href="https://calisthenics-parks.com/" target="_blank">find one</a>.</p>
Recruit a Friend<p>People who workout together stay healthy together.</p><p><a href="https://bmcgeriatr.biomedcentral.com/articles/10.1186/s12877-017-0584-3" target="_blank">One study</a> showed that older adults who exercised with a group improved or maintained their functional health and enjoyed their lives more.</p><p>Enlist the help of a walking buddy with a regimen you aspire to have. If you don't know anyone in your area, apps like <a href="https://www.strava.com/" target="_blank">Strava</a> have social networking features so you can get support from fellow exercisers.</p>
Try Meditation<p>According to the <a href="https://www.nccih.nih.gov/research/statistics/nhis/2017" target="_blank">2017 National Health Interview Survey</a>, published by the National Institutes of Health, meditation is on the rise, and for good reason.</p><p>Researchers <a href="https://pubmed.ncbi.nlm.nih.gov/29616846/" target="_blank">found</a> that mind-body relaxation practices can regulate inflammation, <a href="https://www.healthline.com/health/biological-rhythms" target="_blank">circadian rhythms</a>, and <a href="https://www.healthline.com/health/glucose" target="_blank">glucose</a> metabolism, as well as lower <a href="https://www.healthline.com/health/high-blood-pressure-hypertension" target="_blank">blood pressure</a>.</p><p>"Any form of exercise can be turned into a meditation of some type, either by the surroundings you are walking in, like a park or trail, or by blocking out the outside world with music on your headphones," Rue says.</p><p>You can also play a podcast or download an app like <a href="https://www.headspace.com/headspace-meditation-app" target="_blank">Headspace</a> that has a library of guided meditations to practice while you walk.</p>
Do Fartlek Walks<p>Typically used in running, fartlek intervals alternate periods of increased and decreased speed. These are <a href="https://www.healthline.com/nutrition/benefits-of-hiit" target="_blank">high-intensity interval training (HIIT)</a> workouts, which allow exercisers to accomplish more in less time.</p><p><a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0154075" target="_blank">One study</a> showed that 10-minute interval training improved <a href="https://www.healthline.com/health/metabolic-syndrome" target="_blank">cardiometabolic</a> health, or lowered the risk of heart disease, stroke, and diabetes, just as well as working out at a continuous pace for 50 minutes.</p><p><a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0111489" target="_blank">Research</a> also shows that HIIT workouts increase muscle <a href="https://www.healthline.com/health/fast-twitch-muscles" target="_blank">oxidative</a> capacity, or the ability to use oxygen. To do a fartlek walk, try walking at an increased pace for 3 minutes, slow down for 2 minutes, and repeat.</p>
Gradually Increase Pace<p>A faster walking pace is associated with a lower risk of <a href="https://www.healthline.com/health/copd" target="_blank">chronic obstructive pulmonary disease (COPD)</a> and respiratory diseases, according to a <a href="https://pubmed.ncbi.nlm.nih.gov/30303933/" target="_blank">2019 study</a>.</p><p>Still, it's best not to go from a stroll to an Olympic-worthy power walk in a day. Instead, increase your pace gradually to prevent injury.</p><p>"Start by walking at a brisk pace for about 10 minutes per day, 3 to 5 days per week," Rue says. "Once you've done this for a few weeks, increase your time by 5 to 10 minutes per day until you get to 30 minutes."</p>
Add Stairs<p>You've likely heard that taking the stairs instead of an elevator is a way to add more movement into your daily routine. It's also a way to step up your walking. Stair climbing has been shown to <a href="https://www.sciencedirect.com/science/article/pii/S2211335519301123?via%3Dihub" target="_blank">decrease the risk of mortality</a> and can easily add a bit more challenge to your walk.</p><p>If you don't have stairs in your home, you can often find them outside a local municipal building, train station, or at a high school stadium.</p>
Is Your Walk a True Cardio Workout?<p>Not all walks are equal. A walk that's too leisurely may not provide enough burn to qualify as cardio. To see if you're getting a good workout, try to <a href="https://www.healthline.com/health/how-to-check-heart-rate" target="_blank">measure your heart rate</a> using a monitor.</p><p>"A target goal for a good walking workout heart rate is about 50 to 70 percent of your maximum heart rate," Rue says, adding that maximum heart rate is <a href="https://www.healthline.com/health/fitness-exercise/fat-burning-heart-rate" target="_blank">typically calculated</a> by 220 beats per minute minus your age.</p><p>You can also monitor how easily you can carry on a conversation while you walk to gauge your heart rate.</p><p>"If you can walk and carry on a normal conversation, that's probably a lower intensity walk," says Rue. "If you are slightly breathless but can still have a conversation, that's probably a moderate workout. If you are out of breath and can't talk normally, that's a vigorous workout."</p>
Takeaway<p>By shaking up your routine, you can add excitement to your workout and reap even more rewards than a basic walk provides. Increasing the pace and intensity of a workout will make it more effective.</p><p>Simply pick your favorite variation to add some spice to your next walk.</p>

Summer and fall are great seasons to enjoy the outdoors. But if you're already spending extra time outside because of the COVID-19 pandemic, you may be out of ideas on how to make fresh-air activities feel special. Here are a few suggestions to keep both adults and children entertained and educated in the months ahead, many of which can be done from the comfort of one's home or backyard.
The coronavirus may linger in the air in crowded indoor spaces, spreading from one person to the next, the World Health Organization acknowledged on Thursday, as The New York Times reported. The announcement came just days after 239 scientists wrote a letter urging the WHO to consider that the novel coronavirus is lingering in indoor spaces and infecting people, as EcoWatch reported.
