Once the reactor has shut down, there remains "decay heat" from traces of other radioactive isotopes.
Biological organisms absorb and store radioactive isotopes incorporated in the tissues that make up the organisms.

If he fails to make it in radioactive isotopes, Inwentash has another chance to strike it big in oil.
South Korean experts say they have not detected any radioactive isotopes from North Korea's nuclear test, hampering efforts to assess the device.
These primordial meteorites contain compounds that can only have formed from the decay of radioactive isotopes produced when a star explodes in a supernova.
But a well-contained test could yield no radioactive isotopes, experts say.

FORBES: Radiation Detected In Drinking Water In 13 More US Cities, Cesium-137 In Vermont Milk
Radioactive isotopes accumulate in milk after they spread through the atmosphere, fall to earth in rain or dust, and settle on vegetation, where they are ingested by grazing cattle.

The danger from nuclear waste comes mainly from dust-like particles containing radioactive isotopes of iodine, cesium and strontium that could be released if the reactor fuel is allowed to become too hot.
An analysis from 12 monitors nationwide found "slightly higher" levels of radioactive isotopes in Alaska, Alabama, California, Guam, Hawaii, Idaho, Nevada, Saipan, the Northern Mariana Islands, and Washington state over the past week, the agency said.
