Why is a beta-gamma source that is shielded with a relatively thin sheet of aluminum effectively a gamma source?
Coursepivot September 6, 2022 05:09
Verified Answer \gamma-γ− particles are neutral in nature and \beta-β− particles are charged particles. Hence \gamma-γ− particles do not interact as strongly as \beta-β− particles do. Due to the strong (View full solution)

Was there a large difference in the percent errors of the experimental mass absorption coefficients? If so, why do you think this was the case?
Coursepivot September 6, 2022 05:09
Explanation The count rate in the experiment is much greater than the theoretical value as the detector measures all types of radiations it is interacting with. These radiations include gamma (View full solution)

What is the mass absorption coefficient, and what are its units? Are there any advantages to using the mass absorption coefficient rather than the linear absorption coefficient? Explain.
Coursepivot September 6, 2022 05:08
Explanation There are two types of absorption coefficients, they are linear absorption coefficient (LAC) and mass absorption coefficient (MAC). MAC is a constant describing how readily a given radiation can (View full solution)

Explain how a source that has only one radioactive isotope can emit both beta and gamma radiation.
Coursepivot September 6, 2022 05:08
Explanation Radioactive isotopes have different masses but the same atomic number. They have unstable nuclei and dissipate energy by spontaneously releasing radiation in the form of \alphaα, \betaβ and \gammaγ (View full solution)

On what parameters does the absorption of nuclear radiation depend?
Coursepivot September 6, 2022 05:07
Explanation Nuclear radiation is the energy given off when the radioactive elements break down into more stable atoms. The amount of absorption depends on the type of the radiation, energy, (View full solution)
