Several feet of concrete or a few inches of dense material (such as lead) can block these types of radiation. One of the best ways to be prepared is to understand the principles of radiation protection of time, distance and shielding. During a radiological emergency (a large release of radioactive material into the environment), we can use these principles to help protect ourselves and our families. Almost any material can act as a shield against gamma rays or x-rays if used in sufficient quantities.
Different types of ionizing radiation interact in different ways with the shielding material. The effectiveness of the shield depends on the braking power, which varies with the type and energy of the radiation and the shielding material used. Therefore, different shielding techniques are used depending on the application and the type and energy of the radiation. The apparent attenuation coefficient of wood in this study is not officially approved as a parameter in nuclear physics; however, this type of information is useful for people who actually live in a polluted environment.
An accident at a nuclear power plant, a nuclear explosion, or a dirty bomb are examples of radiation emergencies. It is necessary for all citizens to consider how to protect themselves against radioactive materials and the consequences every time a nuclear accident occurs. In a large-scale radiological release, such as an accident at a nuclear power plant or a terrorist incident, the following tips have been proven and proven to provide maximum protection. Occupational hazards from airborne radioactive particles in nuclear and radiochemical applications are greatly reduced by the widespread use of glove boxes to contain such material.
According to the “Monitoring Information of Environmental Radiactivity Level” report, provided by MEXT 2 months after the disaster, at least some of the radionuclides, such as I-131, Cs-134, Cs-137, Te-129m, Te-132 and Sr-89, were detected in Sugitsuma, Fukushima, which is located 62 km northwest of Fukushima Daiichi Nuclear Power Plant. Workers exposed to radiation, such as radiographers, workers at nuclear power plants, doctors who use radiation therapy, those who work in laboratories that use radionuclides, and hazardous materials equipment must use dosimeters in order to record occupational exposure. Residents who lived within a 20 km radius of the nuclear power plant were evacuated shortly after the disaster. Workplace radiation is a serious concern, but nuclear protection products exist to protect workers in medical facilities and nuclear power plants.
Lead shielding, often used in a variety of applications, including diagnostic imaging, radiation therapy, nuclear and industrial shielding. Shielding with wood and paper with a thickness of approximately 20 mm proved to be useful in reducing radiation due to radioactive fallout from the Fukushima Daiichi nuclear power plant.
