    8. A gamma radiation source (226Ra) is used in a hospital laboratory. If shielding is considered as a means of control, how many centimeters are needed to reduce the radiation to 1% of what a worker would be exposed to without shielding?

    Assume the shielding material is (a) concrete, (b) steel and (c) lead. (Note: You will need to us the half-thicknesses of each material)
    Concrete: Half thickness = 11.938cm
    Steel: Half thickness = 1.778cm
    Lead: Half thickness = 1.378cm

    The radiation intensity reduced by the absorber is given by the following equation:

    I=Io*exp(-m*x), (eq.1)

    where m is the absorbtion koeffitient.
    the half thickness k and ...

    Solution Summary

    The radiation intensity reduced by the absorber is given by the following equation: I=Io*exp(-m*x)
