Answer 1

Answer 6- correct

There are two types of the biological effects of radiations, deterministic and stochastic.

Answer 7- correct

All early effects, and most normal tissue late effects are deterministic

Answer 8- wrong

To minimize bremsstrahlung production, this shield should have low Z, and it can be enclosed in another material (high Z) that is thick enough to attenuate the bremsstrahlung intensity.

Answer 9- correct

The ionization cannot be used as measure for the amount of exposure which the material had to radiation

Answer 10- wrong

The absorbed dose in rad per roentgen of exposure is known as the roentgen-to-rad conversion factor F.
