Abstract
It is important for the BNCT community to be able to compare and predict the biological effects of mixed radiation fields at various centres. A quantitative comparison of the beams would allow more valid discussions of radiobiological and clinical data between centres. If a biological system could be irradiated in various BNCT facilities and its radiation response analysed such a comparison will be possible. If the beams at each centre can thus be compared the preclinical and radiobiological studies performed at other centres will not have to be repeated at new centres, such as at Birmingham, and comparison of clinical data will be more meaningful.
This report describes the design of an in vitro experiment which fulfils these criteria. Cell survival will be determined in relation to the depth in a phantom following irradiation in a BNCT beam. To overcome the problems of the variable repair of sub- lethal damage from the gamma radiation component of any beam during the irradiation period all irradiations will be performed at 4°C The different components of the total dose rate at each position in the phantom will be estimated using paired ionisation chambers and activation foils. To ensure that a valid comparison is being made, the beam survival curves will be compared to x-ray survival curves produced at each centre in this study.
