Radiation Safety and Contamination

The video explains key terms in radiation emergencies, focusing on exposure and contamination. Exposure is the energy from radioactive material that can harm the body, while contamination involves radioactive material on or inside a person. Decontamination can remove external contamination, and internal contamination may require medical treatment. In emergencies, the best actions are to get inside, stay inside, and stay informed.

What is the primary difference between contamination and exposure in a radiation emergency?

• Both involve radioactive material.

• Both involve energy release.

• Exposure involves energy release, contamination involves radioactive material.

• Contamination involves energy release, exposure involves radioactive material.

How can exposure to radiation be stopped?

• By washing off the radioactive material.

• By moving away from the radiation source.

• By consuming special medication.

• By wearing protective clothing.

What is the main source of harm in radiation exposure?

• Radioactive material on the skin.

• Contaminated food and water.

• Direct contact with radioactive objects.

• Energy released from radioactive material.

What does decontamination involve?

• Moving away from the radiation source.

• Washing off external radioactive material.

• Consuming special medication.

• Wearing protective clothing.

What is the process called when external radioactive material is removed from a person?

• Internal contamination

• Exposure

• Radiation shielding

• Decontamination

What is internal contamination?

• Radiation exposure from a distance.

• Radioactive material inside the body.

• Radioactive material on the skin.

• Energy passing through the body.

What is the risk of exposing others if a person has internal contamination?

• Very little risk of exposure to others.

• No risk of exposure to others.

• Moderate risk of exposure to others.

• High risk of exposure to others.

What should you do if you suspect internal contamination?

• Try to wash it off.

• Seek medical help for potential treatments.

• Ignore it as it poses no risk.

• Stay away from others to prevent exposure.

What is the role of doctors or public health officials in cases of internal contamination?

• They help remove contamination with special treatments.

• They provide protective clothing.

• They monitor radiation levels.

• They evacuate the contaminated area.

What is the recommended action to take during a radiation emergency?

• Stay outside and monitor the situation.

• Get inside, stay inside, and stay tuned for information.

• Wait for instructions before taking any action.

• Evacuate immediately without any information.
