Dose distributions and mean doses in cylindrical cavities of bone marrow on X-ray irradiation

Dose distributions as well as mean doses to cylindrical cavities of bone marrow on X-ray irradiation have been calculated using (a) Monte Carlo method and (b) a simplified straight line approximation method. The results are compared with earlier published ones. Point doses differ appreciably from the earlier results by as much as 40 percent at some points, whereas mean doses agree to within 10 percent for all the three methods.
