概要
- 論文の詳細を見る
A new type of β-ray calibration source was designed for estimating tissue doses from skin contamination. Thin polyethylene ion-exchange membranes were applied for the source preparation. The method of determining tissue absorbed dose rates with an extrapolation chamber was discussed for the calibration sources prepared with <SUP>147</SUP>Pm, <SUP>204</SUP>Tl and <SUP>90</SUP>Sr-<SUP>90</SUP>Y. The influence of backscattered β-rays by source mount materials was estimated as a function of membrane source thickness. The membrane sources are quite suitable for the present purpose, because they have large uniform radioactive areas and can be easily handled without radioactive contamination.
