OSHA 30 - Module 22: Ionizing and Non- Ionizing Radiation Safety Questions and Answers Rated A+

OSHA 30 - Module 22: Ionizing and Non- Ionizing Radiation Safety Questions and Answers Rated A+ What is ionizing radiation? Radiation that has enough energy to remove electrons from atoms and molecules. What is non-ionizing radiation? Radiation that does not have enough energy to remove electrons from atoms. What is the main difference between ionizing and non-ionizing radiation? Ionizing radiation can alter atomic structures, while non-ionizing radiation cannot. What are common sources of ionizing radiation? X-rays, gamma rays, and radioactive materials. What are common sources of non-ionizing radiation? Microwaves, radio waves, and ultraviolet (UV) light. 2 What is the primary health concern with exposure to ionizing radiation? It can damage DNA, leading to cancer or other health issues. What type of radiation is used in medical X-rays? Ionizing radiation. How does ionizing radiation affect living cells? It can cause cell death or mutations, potentially leading to cancer. What is the unit used to measure ionizing radiation dose? The sievert (Sv) or millisievert (mSv). What protective measures are used to minimize exposure to ionizing radiation? Increasing distance, using shielding, and reducing exposure time. What is the main health risk associated with prolonged exposure to non-ionizing radiation? It can cause burns or heat-related injuries in high exposures, but typically does not cause cancer. 3 What is the difference between alpha and beta particles in terms of their ability to penetrate materials? Alpha particles are stopped by a sheet of paper, while beta particles can penetrate paper but are stopped by materials like plastic or glass. How does shielding protect workers from ionizing radiation? It absorbs or blocks radiation, reducing the amount that reaches the worker. What safety equipment is recommended for protecting workers from ionizing radiation? Lead aprons, radiation suits, and dosimeters. What role does a dosimeter play in radiation safety? It measures a worker's exposure to ionizing radiation over time. What are the potential effects of overexposure to ionizing radiation? Radiation burns, increased cancer risk,
