Theory of RBE. Technical progress report
Dye films and alanine are being studied for application as dosimetric substances in relation to track theory. The objective is to test track theory with dosimeters whose sensitive target is about one manometer in size. Results with the dye films give good agreement with a slightly modified track theory. Cellular radiosensitivity parameters have been fitted to inactivation data obtained with particles up to neon, in the grain-count regime, and then returning to the basic model of a single on-target detector to calculate the track width regime. A new model has been created for the formation of etchable tracks in plastics. The model is consistent with some published data for CR-39, and suggest this material is another 1-hit detector. (ACR)
