	[Navert Stephan]  At the PSI proton accelerator (590 MeV,
research, tumor treatement and Isotope production) in switzerland, the
dosimetry is done with TLD (for gamma and Betas) and with CR-39
dosemeters for neutrons (replacement for U-foil n-Detectors). This
procedure is accepted by the authority. 

	Hope this helps.
