Radiation safety encompasses practices and protocols designed to protect individuals and the environment from the harmful effects of ionizing radiation. This includes minimizing exposure through key principles like the ALARA (As Low As Reasonably Achievable) concept, which emphasizes reducing the time spent near radiation sources, maximizing distance from them, and employing effective shielding materials such as lead or concrete. Common sources of radiation include medical imaging devices, nuclear power plants, and naturally occurring elements like radon gas. Protective measures involve using personal protective equipment (PPE) such as lead aprons, dosimeters for monitoring exposure levels, and engineered controls like interlocks and barriers. In various fields, such as healthcare, industry, and research, adherence to international standards set by organizations like the International Atomic Energy Agency (IAEA) ensures safe handling, storage, and disposal of radioactive materials, ultimately preventing acute effects like radiation burns and long-term risks such as cancer. Regular training, risk assessments, and emergency response plans further promote a culture of safety to safeguard public health and the ecosystem.

A. As Low As Reasonably Achievable
B. Always Limit All Radiation Access
C. Absolute Level of Radiation Absorption
D. Advanced Laboratory for Radiation Analysis
Answer: A. As Low As Reasonably Achievable
Explanation: ALARA emphasizes minimizing radiation exposure to the lowest possible level using practical means, reducing health risks.
4. Which of the following is a biological effect of acute high-dose radiation exposure?
A. Hair loss
B. Sunburn
C. Radiation sickness
D. Mild fatigue
Answer: C. Radiation sickness
Explanation: Acute exposure can cause radiation sickness due to damage to rapidly dividing cells, leading to symptoms like nausea and vomiting.
5. What is the main purpose of a dosimeter in radiation safety?
A. To detect radiation leaks
B. To measure personal radiation exposure
C. To shield against radiation
D. To store radioactive materials
Answer: B. To measure personal radiation exposure
Explanation: Dosimeters, like film badges, monitor and record the amount of radiation an individual receives, ensuring exposure limits are not exceeded.
6. Which organization sets international standards for radiation protection?
A. WHO
B. IAEA
C. ICRP
D. FDA
Answer: C. ICRP
Explanation: The International Commission on Radiological Protection (ICRP) develops guidelines to protect people and the environment from radiation hazards.
7. What is the recommended distance to maintain from a radiation source to reduce exposure?
A. As close as possible
B. At least 1 meter
C. Increase distance proportionally
D. No specific distance
Answer: C. Increase distance proportionally
Explanation: Exposure decreases with the square of the distance from the source, following the inverse square law, which helps in minimizing dose.
8. Which protective measure involves using barriers to block radiation?
A. Time reduction
B. Distance increase
C. Shielding
D. Contamination control
Answer: C. Shielding
Explanation: Shielding uses materials like lead or concrete to absorb radiation, preventing it from reaching personnel and reducing exposure.
9. What is the half-life of a radioactive substance?
A. The time it takes to decay completely
B. The time for half of the atoms to decay
C. The total lifespan of the substance
D. The rate of emission per second
Answer: B. The time for half of the atoms to decay
Explanation: Half-life determines how quickly a radioactive material loses its radioactivity, aiding in safe handling and storage decisions.
10. Which of the following is a stochastic effect of radiation exposure?
A. Skin burns
B. Cancer induction
C. Radiation cataracts
D. Acute nausea
Answer: B. Cancer induction
Explanation: Stochastic effects, like cancer, have a probability of occurring without a threshold dose, increasing with higher exposure levels.
