Abstract
The phenomenon of hyper-radiosensitivity (HRS) to very low acute single doses of radiation has been demonstrated in several cell lines in vitro and in vivo, and has been studied in theory and in practice. The theory suggests a similar hypersensitivity when cells are continuously exposed to radiation at very low dose rates. These low dose rates are used when radioactive seed (iodine-125 or palladium-103) implants of the prostate are used as an alternative to surgery or external beam radiotherapy. To investigate the radiobiology of hypersensitivity of this type on various cell lines in vitro, an iodine-125 seed irradiator has been designed and built for safe use in the Gray Laboratory. In practice, the calculated dose rate has been used for consistency. Discrepancies between calculated and measured dose rates are discussed.
