Answer: a. Genetically significant dose
Step-by-step explanation:
Genetically significant dose is the index of radiation that is received by the genetic pool. It determines the progeny of the given population. This can be achieved by weighting the individual dose of the gonads that is received by the x-ray examination or ionization imaging by the individuals being examined also by the contribution of those persons to the expected number of children to be born in future.
It represents an estimate of the genetic significance of gonad radiation doses.
