Development of neutron-sensitive glass dosimeter containing isotopically enriched boron

Neutron-sensitive glass dosimeters were successfully made from reagents of NaPO3, Al(PO3)3, enriched 10 or 11B2O3 and AgCl. The glass dosimeters had good RPL characteristics: satisfactory linearity of 0.01–500 mGy and low variation in sensitivity. The RPL characteristics for gamma-rays were compatible with those of a commercial glass dosimeter. A pair of the 10 or 11B-containing glass dosimeters was effectively used for the thermal neutron dosimetry. In 565 keV and 5.0 MeV monoenergetic neutron calibration fields, albedo neutrons from the ISO water slab phantom were successfully detected with the glass dosimeter pairs.
