| Abstract:: |
| By means of a water-filled phantom the detective efficiency of a shadow-shieldvhole-body counter was calibrated.The effidency curves for different ratio of the weight and height of the body with lifferent energies of γ-quantum under three conditions were obtained and compared
vith those of the "reference man" phantom.In additon,a controlled variable speed canning method was recommended,which might improve the uniformity of the space esponse and reduce the effect of uniformity of the distribution of radionuclide in body,and hence the accuracy of the measurement was improved. |
