Accumulation Of Tc Research Articles

Accumulation of 99Tc by tumbleweed and cheatgrass grown on arid soils.

AbstractThe accumulation of Tc by tumbleweed and cheatgrass was measured for five soils at one, two, and three months' harvest times. The initial soil concentration of 1.0 pg 99Tc/g added to the soil as pertechnetate, was traced by 95mTc. At the three month harvest time, uptake of the added Tc range
