The risks of radiation exposure are downplayed and easily dismissed as “irrational fear” because the physics and chemistry of the fission process and the radioactive elements it produces are complex and not understood by the general public and also because, except in cases of acute radiation poisoning, radiation is invisible.

Radioactive fission products are “variant forms of the ordinary chemicals which are the building blocks of all material and living things,” explains Dr. Rosalie Bertell in her book, No Immediate Danger: Prognosis for a Radioactive Earth. The difference is that stable, non-radioactive atoms have an equal number of protons and electrons.

Nuclear fission creates an imbalance between protons and electrons, producing enormous quantities of hundreds of different radioactive elements — the high-level waste and activation products — all of which seek to return to a stable state. These unstable atoms become stable by knocking out the extra particles fission created, a process she says takes hundreds of thousands of years.

“Every such release of energy is an explosion on the microscopic level,” Bertell says. Radiation exposure is particularly damaging to the structure of cells, which is why it is necessary to keep these radioactive elements, known as radionuclides or radioisotopes, out of the bodies of humans, other living beings and the environment.

As climate models have long predicted, our warming world is now experiencing much larger and stronger storms with significantly more rainfall in the Earth’s wetter areas and more sustained and severe drought and wildfires in the drier regions. In 2019, the hottest June on record triggered an unprecedented fire season in the Arctic, with over 100 intense fires. The summer of 2019 also saw 55 billion tons of water melt off Greenland’s ice sheet in just five days, a rate scientists hadn’t expected for 50 years.

A month before the massive ice loss in Greenland, scientists predicted sea levels could rise 6.5 feet by the end of the century, submerging nearly 700,000 square miles of land.

Most nuclear power plants are located beside rivers, lakes, dams or oceans because they need a continuous source of water to cool the reactors. In August 2018, Ensia reported that at least 100 nuclear power plants built a few meters above sea level in the U.S., Europe and Asia would likely experience flooding due to sea level rise and storm surges.

Though nuclear reactors vary in generating capacity, 1,000 megawatts is common. A reactor of that size contains 100 metric tons of enriched uranium fuel, roughly a third of which needs to be replaced with fresh fuel each year. According to radioactive waste expert Dr. Marvin Resnikoff, the spent fuel, also known as high-level waste, becomes 2.5 million times more radioactive after undergoing nuclear fission in the reactor core.

In a May 2011 report, Institute for Policy Studies (IPS) senior scholar Robert Alvarez, a top official at the U.S. Department of Energy from 1993 to 1999, described the danger of high-level waste this way: “Spent fuel rods give off about 1 million rems (10,000 sieverts) of radiation per hour at a distance of one foot — enough radiation to kill people in a matter of seconds.”

The intense radioactivity the fission process creates is why reactor cores are surrounded by five-feet thick reinforced concrete containment structures and spent fuel must be shielded by at least 20 feet of water in pools for several years after it leaves the reactor.

As of September 2019, 444 nuclear reactors are operating in the world, with 54 under construction, 111 planned and 330 more proposed.https://truthout.org/articles/can-nuclear-powers-deadly-waste-be-contained-in-a-warming-world/?eType=EmailBlastContent&eId=a5fbaf3b-857d-46f7-9571-6774775ad709
