Reducing Radiation Risk

The video discusses the applications of radioactive substances in medicine and nuclear power. It explains the need for radiation detection tools like Geiger counters, which help monitor radiation levels. The video also covers safety measures for workers handling radioactive materials, such as wearing protective clothing, using film badges, and employing shielding techniques to minimize exposure.

What are some applications of radioactive substances mentioned in the video?

• In medicine for X-rays and cancer treatment

• In space exploration

• In agriculture for pest control

• In food preservation

Why is it necessary to use devices like Geiger counters when working with radioactive materials?

• Because they can store radioactive materials safely

• Because they can eliminate radiation

• Because they can detect radiation that is invisible to human senses

• Because they can convert radiation into electricity

What is the purpose of wearing film badges in nuclear power plants?

• To protect against chemical spills

• To measure the dose of radiation received over time

• To enhance communication between workers

• To monitor air quality

Which of the following is a method to reduce contact with radioactive materials?

• Using soundproof barriers

• Using machines to handle the source

• Increasing the temperature of the environment

• Applying chemical neutralizers

What should always be done to radioactive substances due to their dangerous nature?

• They should be mixed with non-radioactive materials

• They should be marked with the radiation warning symbol

• They should be stored in glass containers

• They should be exposed to sunlight
