Achieve the Safety Measures with the Use of Effective Shielding
Posted: Nov 09, 2018
There are many applications that cause harmful radiation to be directed over human beings. This should be avoided by the application of proper shielding. Latest technologies create physical barriers in order to protect from hazardous radiation. Shielding materials generally perform an attenuation of the radiation by easing the removal of heat along with the resistance to the damage created by the radiation.
The shielding materials are chosen based on the intensity of the radiation that is exposed to the individuals. The radiologic application demands such shielding materials to be used. In certain medical applications, the intensive radiation is used to diagnose and treat the patients to cure severe health complications. In these cases, proper protection of the radiation should be carried out.
Things that make shielding an essential element
Any material can serve as radiation shielding to protect from the gamma or x-rays that are exposed. The shielding effectiveness depends on the intensity of the radiation particles. Shielding helps to reduce the noise that is created in the background for detectors.
This shielding attenuates the radiation by blocking the particles of the ray with the barrier material. Charged particles attenuate when they undergo the reactivity with the electrons that are present in the barrier. Neutrons are converted to reduce harmful with either through the elastic or inelastic scattering.
When the radiation shielding materials are used even the higher energy levels of the ultraviolet rays can be shielded with the proper methods such that it does not create any complication issues in individuals. Neutron shielding can also be applied either positive or negative where the energy levels are blocked to achieve the shielding.
Neutron shielding can be achieved by using the material lead where the neutrons get uncharged by passing over the dense materials. Materials comprising decreased atomic number blocks the radiation as they possess the increased probability to form cross-sections that interact with the neutrons.
In the case of alpha and beta radiation, the positive charge helium nuclei of alpha can be blocked easily whereas the beta particles are negatively charged which is difficult to shield. Radiation shielding executed under the guidance of the professionals to obtain the extraordinary protection from the radiation.
Considerations of shielding materials
The exposure of the radiation over the certain materials creates a degradation of the materials under specific conditions such that the metals when undergoing radiation exposure may lead to the alteration in their mechanical properties. Similarly in the case of concretes may tend to become weak though they are strong and durable.
The selection of the radiation shielding materials consider the main factors like attenuation, the strength of the radiation and tolerance level to damage. The thermal properties should be taken into account along with the efficiency in cost plays a vital role in offering radiation protection.
Mostly hydrogen based materials are used to perform this operation. Water contains hydrogen atoms which serve as a high concentration hydrogen atom to shield the neutrons. Thus the shielding assists in to protect the individuals from hazardous radiation undoubtedly.
