Investigation of dosimetric properties of barium and strontium dithionates

An investigation is made of the dosimetric properties of proposed spin-resonance γ-radiation dose meters based on Ba and Sr dithionates. Their operating range (0.1 Gy−50 kGy for Ba dithionate and 0.2 Gy−80 kGy for Sr dithionate) is established. Their advantages over the EPR/L-α dose meter are discussed: the narrow isotropic EPR signal, higher radiation sensitivity, large range of linear response. Conditions of storage and use of dithionate-based dose meters (temperature of 15–25°C, relative air humidity no more than 80%) are determined.
