Accident Dosimetry of Weakly Penetrating Radiation Utilising Carbon Loaded LiF Pellets in a Mylar Phantom [Elektronische Daten] [T. Wøhni] A dosemeter for measuring depth dose profiles in skin from weakly penetrating radiation, utilising carbon loaded LiF pellets embedded in a Mylar phantom has been developed. The purpose of the dosemeter is to assess skin doses at various depths in order to evaluate the stochastic and deterministic effects of large skin exposures. The dosimetric thickness of the pellets is approximately 9 mg.cm2, and their response to low energy photon radiation and to beta radiation have been measured. For photons, the sensitivity of the pellets drops dramatically below 8 keV, due to internal self shielding. The response to low energy betas from 147Pm was found to be 0.38 of the corresponding 90Sr/90Y response. Information from the measured depth-dose profile can be used to correct for the self shielding under response. Measured depth-dose profiles for different soft X ray spectra, illustrating different self shielding under response factors, are presented. Measured depth dose profiles from 90Sr/90Y and 204Tl beta sources are also shown, and compared with published beta depth-dose profiles calculated by Monte Carlo methods.
