Calculation and verification of the spectrum-dose conversion operator of various CsI(Tl) scintillation counters for $$gamma$$-ray

Tsuda, Shuichi  ; Tsutsumi, Masahiro

The spectrum-dose conversion operators (hereafter, G(E) function) for CsI(Tl) scintillation counters with various crystal sizes were calculated based on the response functions obtained by a Monte Carlo simulation code, MCNP5. The G(E) functions were determined in the cases of crystal sizes 5.5$$times$$5.5$$times$$5.5, 10$$times$$10$$times$$10, 13$$times$$13$$times$$20 and 38$$times$$38$$times$$25 mm$$^{3}$$ for ambient dose, H*(10). It is found that the values of H$$^{*}$$(10) deduced from the pulse-height spectra and the G(E) function agree with those of H$$^{*}$$(10) evaluated in the calibration field in JAEA within 2% in the case of irradiations by a $$^{137}$$Cs, $$^{226}$$Ra and a $$^{60}$$Co source, by the measurements using a scintillation counter whose crystal size is 13$$times$$13$$times$$20 mm$$^{3}$$.
