3. What is radiation protection? Radiation protections also known as radiological protection is defined as the protection of people from harmful effect of exposure to ionization radiation and the means for achieve this. Principle of radiation protection stage 1. Why we need radiation protection stage 2. Aim of radiation protection stays 3. How we achieved it ? 4 . ALARA principle 5. Time Distance shielding

4. 1. Organ Atrophy : It is the reduction in size of Organ after attaining its normal mature growth. 2.Hereditary Effects: It may cause damage to genetic material which can lead to genetically induced disease. 3. Damaging DNA: Is an alteration of DNA structure that is capable of crossing cellular injuries and reduce reproductive fitness of the organism 4. Radiation Peakness: Is damage to your body caused by a large dose of radiation after receiving over a short period of time 5. Serious health Problem: Such as cancer 6. Damage Tissue: The most common soft tissue injured are muscle tendons and ligaments Why We Need Radiation Protection?

5. Aim of Radiation Protection The aim of radiation protection is to prevent the harmful effect on the body and also prevent the effect who cause after long period of time and acute effects. How we Achieved it ? Radiation exposure limit were introduced by the international commission on radiology protection in 1928. So this could be achieved by using principle ALARA of principle, this principle mean that even if it is small dose, if receiving that dose has no direct benefit, you should try to avoid it. To do this, you can use three basic protective measure in radiation, safety time, distance and shielding.

6. Three principle used in radiation protection are 1. Time- Time actually means you have to reduce the produce the time which is result having a low exposure. This matter also reduce the change of biological effect. 2.Distance- Distance between patient and a source is approximately so mentioned by the international commission. This follows inverse square law radiation is inversely proportional to the squared distance between source and body. 3.Shielding- To shield yourself from radiation source, you need to put something between you and the radiation source. Use proper lid material to protect any person from unnecessary exposure .

7. What is a dosimeter used for? A dosimeter is an instrument used to measure ionizing radiation exposure (via alpha or beta particles, neutrons, gamma rays, or x-rays) in a science called dosimetry. It is an essential tool for people who work in situations where they are exposed to radiation .

8. What is a TLD badge? TLDs are used for measuring gamma, x-ray, and beta radiation exposures. They can be worn as rings or body badges. They contain small chips of lithium fluoride, which absorb ionizing radiation energy and displace electrons from their ground state.

9. Radiation protection and safety encompass a range of practices, regulations, and technologies aimed at minimizing the risks associated with exposure to ionizing radiation. Key aspects of radiation protection and safety include: 1.Risk Assessment: Evaluating potential radiation hazards and assessing the associated risks to individuals, communities, and the environment. 2. Regulatory Framework: Establishing and enforcing regulations and guidelines to ensure the safe use of radiation sources, radiation-emitting devices, and nuclear materials. 3. Occupational Safety: Implementing measures to protect workers who may be exposed to radiation in various industries, such as nuclear power plants, medical facilities, and industrial settings. 4. Public Safety: Educating the public about radiation risks, implementing measures to limit public exposure to radiation, and responding to radiation emergencies to mitigate potential harm.
