The radioactive contaminant was 60cobalt, After the company discovered the contamination, it was forced to shut down its production for 28 days while it spent more than $2 million in cleanup costs.
Laboratory calculations predicted each radioactive contaminant would tightly bind to the soil, allowing the pollutants to travel a few meters at most.
Because most of Iran's reactors are in full operations, air strikes may mean cutting off the power supply to Iranian citizens and could release large amounts of radioactive contaminants into the air.
And because the 115-meter wide crater was never lined, there are fears radioactive contaminants are leaching through the island's porous coral rock into the ocean.
The signing of the legislation comes on the same week that a federal report was issued saying people who lived near or played in Coldwater Creek from the 1960s to the 1990s may have been exposed to radioactive contaminants, increasing their risk of developing cancer.
Testing for volatile organic compounds, pesticides, metals, nitrate, bacteria, and radioactive contaminants could exceed $500, says Lynda Knobeloch, a former toxicologist with the Wisconsin Department of Health Services who was not involved with the paper.
Buesseler and Charctte led a research team that came to the Marshall Islands in 2015 to study the sources, flow, and extent of radioactive contaminants on Bikini and Enewetak Atolls nearly 70 years after the nuclear battering.
Landslides, flooding and the possible failure of containment barriers are also a concern at the Mailuu-Suu site, which houses a significant amount of residual radioactive contaminants. However, progress is being made.
Using the Chernobyl Nuclear Power Plant disaster in Ukraine as a case study, this volume describes the assessment of groundwater vulnerability and an improved methodology based on integration of the methods of hydrogeological zonation and modeling of anomalously fast migration of radioactive contaminants from the land surface toward groundwater, to aid in evaluating groundwater vulnerability and conducting risk assessments for groundwater contamination from diverse sources, as well as selecting optimal remediation methods for reducing threats from residual radioactivity.
"Radioactivity can be dangerous, and we should be carefully monitoring the oceans after what is certainly the largest accidental release of radioactive contaminants to the oceans in history," Buesseler said, referring to the Fukushima disaster, the world's worst nuclear power plant accident since Chernobyl in 1986.
No one was underground at the Department of Energy Waste Isolation Pilot Plant near Carlsbad, in New Mexico's Southeast, when the alarm went off at 11:30 pm MST on Friday, and none of the 139 employees working above ground at the facility was exposed to radioactive contaminants, he said.
These included mineral supplements he sold for more than five times their market value in Tokyo, as well as costly tests for radioactive contaminants in food and urine.
