    Graphical Abstract
    • Abstract
  • The direct measurement of radioactive solution with a 4πγ Ionization Chamber,which doesn't require for transfering source solution to the specified container inaccordance with the specified weight, is tried and is successful The method whichis used to perform source geometry correction source solution self-absorptioncorrection and container wall absorption correction for the result of direct measu-rement is given. The uncertainty of ion current goes up from 0.34% to 0.6%because of performing these corrections.
