question 4 please
CSDA range
Determine the expected range of 2 MeV beta radiation in polyethylene, Aluminium and air. Use the ESTAR database on the NIST website
to find the CSDA ranges (to 4 significant figures):
R(px) for polyethylene = 9.375E-01
✓g/cm²
R(px) for Al=
1.224E+00
✓ g/cm²
R(px) for air-
1.094E+00
x g/cm²
Looking at the 3 values you have found, the statement in the lab notes that the range is 'inversely proportional to the density p of the
material and not dependent on its structure or any other properties' is
a useful rough approximation because the px values are similar even if not exactly the same
The values given are density times thickness (px). To find the actual range (x) we just divide by the density.
