✦ Synopsis

Computer calculations have been perfumed to determine calibration facg~ of various types of dosnneters in a heavy water moderated "~'Cfand monoenergetic~utron fields, and the mediums being free air and a water phantom. In the case of heavy water moderated "~'Cf source, the neutron spectra from the source was determined with MORSE-CG code. The backu:attered neutron spectra on the surface of the phantom was calculated with MNCP code and then the contribution of these ~ neutrom to the dose equivalent was estimated KEYWORDS CR-39 based neutron dosimeter, bubble detectors, rem counter, calibration figtor, MORSE-CG (axle, MNCP code.
