Most of the plutonium isotopes are alpha-emitters, a fact which is of
decisive importance from a biological point of view. We shall Consider their
potential danger to life in general, and to human life in particular.
In this respect measurement of plutonium concentration in air and soil and
vegetable is the object of systematic tests in numerous countries. This
plutonium occurs in the fallout from atomic bomb tests .A substantial proportion
of these bombs contained pu-239 as explosive. pu-238 was released by the
disintegration of a SNAP - 9A Power Source upon re-entry into the atmosphere
in 1964.
The pu content of soil sample was determined by wet ashing ,anion exchange,
electrolysis and a-spectroscopy. In the present study we obtained the
best condition of electrolysis (time, current) for plutonium and other
transuraniums. The Pu-239 Content in Soil was also determined qualitatively.
