As a result of single intake of 6.3×10^3 Bq of a radionuclide, a particular organ will receive doses of the 0.2 mGy from a low energy beta particles and 0.05 mGy from the alpha particles during next 50 y.  These are the only radiations emitted and this organ is the only one which receives appreciable radiation as the result of the intake. The organ has a weighting factor of 0.05.

a) Specify the committed equivalent dose to the organ.

b) Specify the committed effective dose to the individual.

c) Specify the ALI for this route of intake.
