A mining company wants to build a modern processing plant that is safe for workers. The location of the plant is close to the mining operation, which has inadvertently exposed some sources of radionuclides. Which is the best reason for consulting with a nuclear chemist before building the processing plant?

• to determine the level of radionuclides present

• to explain the health concerns that are related to radiation

• to destroy all the radionuclides in the area immediately

• to conduct tests to see if workers are affected by radiation

Which profession is likely to use a radiation shield?

• dentist

• astronomer

• mathematician

• geologist

Which type of reaction does this diagram represent?

• nuclear fission because an atom is splitting into two fragments

• nuclear fusion because the products that are produced are radioactive

• nuclear fission because a large amount of energy is being released

• nuclear fusion because atomic nuclei combine to form a heavier nucleus
