Sažetak
The use of the chemical dosimetry solution chlorobenzene-ethanol-trimethylpentane (CET) in radiation dosimetry is based on radiolytic formation of hydrochloric acid, which protonates a pH indicator thymolsulphonphthalein. The amount of acid is proportional to dose and can be used as its measure. Based on CET solution an accident and emergency personal dosemeter was designed – a glass vial filled with the solution and inserted into a pen-shaped plastic holder. Using recently constructed optoelectronic reader doses in the range 0.2-15 Gy can be measured. In the present work the results of determination of the radiation-chemical yield, G(HCl), for the CET system, as well as the response of dosemeters in different neutron fields ranging from 0.35 to 19.3 MeV mean energy neutrons, are summarized. The relation of G(HCl) for the CET system to LET of incident heavy charged particles is also evaluated on the basis of the previously published data. From the measured dependence of the G value upon LET of heavy charged particles and data about the LET distribution for monoenergetic neutrons, the response of the CET system to monoenergetic neutrons was calculated. A very good agreement between this calculation and the experimental results for neutrons was obtained. These results enable predictions of the response to be made in radiation fields with the known LET distributions.
