Yield constants of external Bremsstrahlung excited by 90Sr–90Y, 147Pm and 204Tl in CdO and lead compounds
چکیده انگلیسی

Bremsstrahlung yield of 90Sr–90Y, 147Pm and 204Tl in CdO, PbF2, Pb(NO3)2 and PbCl2 has been measured using 3.8 cm×3.8 cm NaI(Tl) crystal and is compared with Tseng and Pratt theory. The Z dependence of external Bremsstrahlung (EB) is also measured and compared with the theory. The Bremsstrahlung photon yield and energy yield constants (K′ and K) are evaluated from the measured and theoretical yields. These values decrease with the increase in Emax of beta. The evaluated K′ and K may be useful to calculate the photon yield and the energy yield, when these beta particles interact with the compounds of modified atomic number ranging from 42 to 73.
