Question

Contamination of radioactive materials are dangerous because it cause
A. Biological magnification
B. Gene mutation
C. Photochemical smog
D. Ozone destruction

Answer 1

Hint: Atoms that decay naturally make up radioactive compounds. They have the ability to emit alpha, beta, and gamma radiation. Because they cannot be turned off like X-ray sources, they are more difficult to control.

Complete answer:
When radioactive material is deposited on or in an object or an individual, it is known as radioactive contamination. When radioactive materials are released into the atmosphere, they can contaminate the air, water, surfaces, soil, plants, houses, people, and animals. Because of the radioactive decay of the contaminants, which causes ionising radiation (such as alpha, beta, and gamma rays) and free neutrons, such pollution poses a danger. The concentration of pollutants, the energy of the radiation being released, the type of radiation, and the proximity of the contamination to body organs all contribute to the degree of threat. It's important to understand that exposure causes the radiation.
Radiation can alter genetic material irreversibly, resulting in a life-threatening disease. Radiation induces genetic mutations in the body, which stimulate the development of cancerous cells. Genetic mutations have a tendency to pass on to future generations.
So, from the above gathered information it can be concluded that the correct option is: (B) Gene mutation.

Note:
Diagnostic radiology, radiation therapy, and radiopharmaceuticals all use radioactive materials. Wherever radioactive materials are processed or radioactive waste items are discarded, there is a risk of radiation. Fires involving radioactive materials have the potential to contaminate a large area.
