Question

a) Determine the range of charged particles emitted from Xenon-135 in uranium. b) Find the flux of gamma rays emitted from Cs-137 after propagating through a 24.3 cm thick concrete slab if the incoming flux is 10% γ /cm-s. What the range of charged particle released from the decay of Radon-222 in air and water? c)

Answer 1

For xenon 135 dN_xe/dt = r x_e summation f phi + lambda_1 N_1 - lambda_xe N_xe - 5a x_e N_xe phi Here lambda_1 rightarrow decay constant phi rightarrow thermal flux since we know thst Radom 222 is most stable isotope Air samples - Radom 222 in air are formed with direct measurement of radon 2 - 5 radons of magnitude higher than that in almost air.
