The photoncutron ambient dose around a 18 MV medical electron lineal accelerator has been measured with LiF:Mg,Ti chips of 3 x 3 x 1 mm inside moderating spheres. During the measurements a water phantom was irradiated in a field of 40 x 40 cm2. Two methods have been considered for comparison. In the first, a TLD-600/TLD-700 pair at the centre of a 25 cm diameter paraffine ...

Lineal energy distributions and linear energy transfer (LET) spectra are being measured at the biomedical facility of the Los Alamos Scientific Laboratory for a negative pion beam having an initial momentum of 168 MeV/c. The results show that the fraction of the dose for lineal energies greater than 50 keV/mum is approximately 2% in the plateau and ...
