According to a report by the Worldwatch Institute on nuclear waste, Karachay is the most polluted (open-air) place on Earth from a radiological point of view. [8] The lake accumulated some 4.44 exabecquerels (EBq) of radioactivity over less than one square mile of water, [6] including 3.6 EBq of caesium-137 and 0.74 EBq of strontium-90. [4]
A recent report on the Sava river in Serbia suggests that many of the river silts contain about 100 Bq kg −1 of natural radioisotopes (226 Ra, 232 Th, and 238 U). [2] According to the United Nations the normal concentration of uranium in soil ranges between 300 μg kg −1 and 11.7 mg kg −1 . [ 3 ]
A radioactive source is a known quantity of a radionuclide which emits ionizing radiation, typically one or more of the radiation types gamma rays, alpha particles, beta particles, and neutron radiation. Sources can be used for irradiation, where the radiation performs a significant ionising function on a target material, or as a radiation ...
