Abstract
Californium-252 promises to be an effective radium substitute in brachy-therapy. In certain situations, such as cancer of the uterus, the dose rate near a linear source may be of interest. Paterson and Parker (see Meredith, 'Radium Dosage-the Manchester System', p.23, 1967), have tabulated the number of milligram hours for various active lengths of radium sources to give 1000 rad at different distances from the centre of the source. Similar results for Cf-252 (microgram hours to give 1000 rad neutron dose) and the results of experimental measurements of neutron depth dose distributions for both single line sources and arrays are reported. Kodak NTA films and a phantom were used. The experimental results are found to agree well with the theoretically predicted results.
