A particle of ionizing radiation creates 4,600 ion pairs in the gas inside a Geiger tube as it passes through. What minimum energy (in J) was deposited, if 21.0 eV is required to create each ion pair?
If all of this energy is converted to thermal energy in the gas, what is its temperature increase (in K), assuming 55.0 cm3 of ideal gas at 0.300 atm pressure? (The small answer is consistent with the fact that the energy is large on a quantum mechanical scale but small on a macroscopic scale. Assume the initial temperature of the gas is 293 K.)
Typical HVL values for X-ray radiation with energy 1 MeV are 3 cm for bone tissues, 2 cm for aluminum,
0.3 cm for lead. Find mass and linear attenuation coefficients if densities are 1.85 g/cm3 , 2.70 g/cm3 , 11.35 g/cm3, respectively.
The linear absorption coefficient of 1 MeV X-rays in water is 7.06 m-1.
How many times will the radiation intensity decrease in a 19.6 cm thick water layer?
