Fallout from nuclear weapons tests in the atmosphere is mainly 90Sr and l37Cs, which have 28.6- and 32.2-y half−lives, respectively. Atmospheric tests were terminated in most countries in 1963, although China only did so in 1980. It has been found that environmental activities of these two isotopes are decreasing taster than their half−lives. Why might this be?

To determine

The cause of environmental activities of the S90r and C137s isotopes are decreasing faster than their half-life.



The fallout from the nuclear weapon test is due to the ground surface.

When the nuclear test is occurs close the ground surface, soil mixes with the highly radioactive fission product from the test...
