![]() Therefore, to help protect yourself from radiation you use shielding. ShieldingĪs ionizing radiation passes through matter, the intensity of the radiation is diminished. This means that the further away you are from the source of the radiation, the less radiation you’ll be exposed to. ![]() Radiation decreases with distance in accordance with the inverse square law. The less time you spend exposed to radiation the lower your dose. To protect yourself from gamma radiation resulting from a nuclear explosion, there are three things to consider: Time Nuclear Radiation Shielding – Gamma & X-ray Gamma radiation though travels at the speed of light. ![]() It is carried by the wind currents (fallout) and eventually falls to the ground and ‘decays’. It can be stopped by a single piece of paper, or an air filter (think of it as a heavy dust particle). The ‘Alpha’ particle (another type of radiation from a nuclear explosion) is also dangerous, but is hardly penetrable. In other words, Gamma and X-ray radiation are of primary concern. “Gamma or X radiation constitutes the principal casualty producing form of ionizing electromagnetic radiation associated with nuclear explosions”. the total thickness of the material used, based on radiation halving thickness valuesĭifferent types of radiation behave in different ways:Īccording to the NATO Handbook On The Medical Aspects Of NBC Defensive Operations,.properties of the shielding material (density is important).the type of radiation itself and the energy thereof.The effectiveness of the material depends on: Radiation shielding is a mass of absorbing material placed between yourself and the source of radiation in order to reduce the radiation to a level that is safer for humans.
