The half value layer expresses the thickness of absorbing material needed for reduction of the incident radiation intensity by a factor of two. In some cases, lead is ineffective in stopping beta particles because they can produce secondary radiation when passing through elements with a high atomic number and density. Likewise, concretes are strong, durable, and relatively inexpensive to produce, but become weaker at elevated temperatures and less effective at blocking neutrons. For gamma and x-ray, the most used shielding materials are lead, tungsten or concrete, depending on the required size of the shielding and the available budget. See 0000040697 00000 n

This includes nuclear power facilities and industrial complexes, to medical facilities where x-rays are used, and any other “radioactive workspaces.” Shielding ability of a material is determined by the thickness of the material required to absorb half of the radiation This thickness of the material is called the half-thickness Radiation that has passed through one half-thickness will be reduced by half again if it passes through another half-thickness (HT) 0000004243 00000 n
The measurements are carried out by determining the transmission of neutrons through the target sample of known thicknesses. A single centimeter of plastic is sufficient for shielding against alpha particles, as is a half-inch of paper. This number refers to the number of protons within an atom, so a lead atom has a relatively high number of protons along with a corresponding number of electrons. 0000005068 00000 n
Use of materials requiring excessive thickness, such as basic concrete (146 lb/ft3), may be Tables of many buildup factors are required because the factor varies with gamma energy, shield material and with shield thickness. Another common way of evaluating radiation shielding is to use the half value, that expresses the thickness of absorbing material which is needed to reduce the incident radiation intensity by a factor of two, or I x =I o / 2. SHIELDING THICKNESS FOR 6TVL ATTENUATION MACHINE ENERGY ©2010 Shielding Construction Solutions 25. For example, metals are strong and resistant to radiation damage, but they undergo changes in their mechanical properties and degrade in certain ways from radiation exposure. Almost any material can act as a shield from gamma or x-rays if used in sufficient amounts. However, low-density materials can compensate for the disparity with increased thickness, which is as significant as density in shielding applications. Considerations such as attenuation effectiveness, strength, resistance to damage, thermal properties, and cost efficiency can affect radiation protection in numerous ways. 0000036578 00000 n

Lead is primarily used as radiation shield for x-rays produced at potentials below 300 KV, whereas concrete is used above 300 KV, as well as for gamma beam installations. Calculated exposure to galactic cosmic radiation (GCR) with shielding by a wall of the same thickness (30 cm) made of various materials. Lead is quite ineffective for blocking neutron radiation, as neutrons are uncharged and can simply pass through dense materials. Lead is particularly well-suited for lessening the effect of gamma rays and x-rays due to its high atomic number. 0000036876 00000 n
Materials composed of low atomic number elements are preferable for stopping this type of radiation because they have a higher probability of forming cross-sections that will interact with the neutrons. When negatively charged beta particles hit a high-density material, such as tungsten, the electrons are blocked, but the target which the barrier is intended to protect can actually become irradiated. 0000039585 00000 n
