1. Calculate the dose rate and the absorbed dose for the Fricke
dosimetric resolution that was irradiated with Co-60 supply throughout three
hrs. The absorbance of the irradiated dosimetric resolution (Fe3+),
measured with UV/Vis-spectrophotometer in 1 cm cuvettes at the
wavelength =304 nm, elevated from zero.01 (preliminary) to zero.203
(irradiated). The molar absorptivity of ferric ions for this
wavelength is ε304 = 2187 L mol1cm1, the density of the
dosimetric resolution is ρ=1.zero24 g/mL, and the tabulated radiation
chemical yield for gamma supply 60Co is 1.6 µmol J1.

2. Calculate the dose rate and the absorbed dose for the ceric
sulfate dosimetric resolution that was irradiated with Co-60 supply
throughout three hrs. The absorbance of the irradiated dosimetric resolution
(Ce4+), measured with UV/Vis-spectrophotometer in 1 cm
cuvettes at the wavelength =320 nm, decreased from 1.01 (preliminary)
to zero.21 (irradiated). The molar absorptivity of ceric ions for this
wavelength is ε320 = 561 L mol1cm1, density of the dosimetric
resolution is ρ=1.025 g/mL and the G worth for the cerous-ion yield is
2.three molecules/100 eV for the gamma supply 60Co.
three. Estimate the impact of alpha-autoradiolysis in the acidic aqueous
resolution of 239Pu with focus of zero.03 mol/L of 239Pu:
a) Contemplating the half-life T1/2=24111 y (=7.60364×1011 sec) and
the alpha power of 5.24 MeV, what’s the weekly dose absorbed in
