Chemistry

In this lesson, we will learn how to describe the key physical properties of gamma radiation and explain its production by certain nuclear decays.

Worksheet

Q1:

A radioisotope emits rays as it decays. For a given thickness of material, which of the following would provide the most effective shielding when handling this isotope?

Q2:

A uranium-237 nucleus decays, emitting a gamma ray with a wavelength of 5.96 pm. What is the energy of this gamma ray in keV?

Q3:

Which of the following is a reason for the number of nucleons (protons and neutrons) not changing on emission of gamma radiation from a radioactive isotope?
