Radiation Shielding Requirements

radiation source shielding

The most basic shielding requirements for radiation protection are dependent upon several factors including the type of radiation, exposure length and distance from the source of the radiation. Different kinds of radiation are emitted with different levels of energy. The greater the energy, the greater the level of shielding to safely guard against it. Alpha radiation is very weak, and the outermost layer of skin is enough to protect against it. Beta radiation requires more protection, such as heavy clothing. However, some beta radiation particles can penetrate and burn the skin. Gamma radiation and x-ray radiation are much stronger and require thick, dense shielding with materials such as lead.

The briefest exposure to gamma and x-ray radiation can be extremely hazardous to the human body. Even extended indirect exposure, such as an x-ray technician in a separate but nearby room close to the x-ray source, requires shielding. For medical and dental patients, the length of direct exposure to x-rays is so brief that a lead vest is all that is necessary.

Radiation is a very serious concern in nuclear power plants, industrial and medical x-ray systems, radioisotope projects, particle accelerator work and other sites. Containing radiation and preventing it from causing harm to employees is a vital part of operating equipment that emits hazardous rays. For Medi-Ray, Inc., preserving human safety and structural material that can be compromised by radiation exposure are over-riding concerns, as well as shielding sensitive materials such as electronic devices and photographic film.

Regulating the effects and degree of penetration of radioactive rays varies according to the type of radiation involved. Indirectly ionizing radiation such as neutrons, gamma rays and x-rays, is a separate category from directly ionizing radiation, which involves charged particles. Different materials are better for different types of radiation and is determined by the interaction between specific particles and the properties of the shielding materials.
