A tongue-shielding radiation stent
The Journal of Prosthetic Dentistry, 1983This article describes a simple technique for fabricating stents to protect the lateral border of the tongue during therapeutic radiation therapy delivered to a unilateral region such as used in treating parotid or retromolar trigone lesions. The technique requires materials that are readily available and expertise that is possessed by all dentists ...

Radiation shielding concrete is the composite made up of cement, water, and heavy weight aggregates. It can shield such radiations as alpha rays, beta rays, gamma rays, X-rays, and neutrons due to its high density and large content of crystal water. Compared with other shielding materials, radiation shielding concrete is cheaper, easier to mold into ...

Shielding for Beta-gamma Radiation
Health Physics, 1993The build-up factor, B, for lead was expressed as a polynominal cubic function of the relaxation length, mu x, and incorporated in a "general beta-gamma shielding equation." A computer program was written to determine shielding thickness for polyenergetic beta-gamma sources without resorting to the conventional "add-one-HVL" method.

Secondary radiations in spacecraft shieldings
Radiation Measurements, 1994Some problems are discussed which relate to the generation of secondary radiation under the effects of heavy charged cosmic ray particles in spacecraft shielding and in biological tissue. Methods for obtaining the total and differential inelastic interaction cross sections are recommended for use in the calculation of heavy charged particle transport ...

Selective Shielding Against Roentgen Radiation
Radiology, 1953Selective exposure of local areas to roentgen radiation is usually simple to accomplish by blocking off all but the exposed area with sheets of lead. If the volume exposed is relatively small, the radiation which is scattered into the shielded regions is apt to be negligible.

Radiation shielding for diagnostic radiology
Radiation Protection Dosimetry, 2015Abstract Scattered radiation makes up the majority of the stray radiation field around an X-ray unit. The scatter is linked to the amount of radiation incident on the patient. It can be estimated from quantities used to assess patient dose such as the kerma-area product, and factors have been established linking this to levels of ...

The Efficiency of Radiation Shields
Review of Scientific Instruments, 1948The effect of a number of thick radiation shields of infinite thermal conductivity and of a type realizable in practice is analyzed by matrix algebra, and a method for calculating the temperatures of the various shields is also given. For identical thin shields it is found that the ratio of the power required to maintain a radiating surface of ...

Radiation exposure is a limiting factor to work in sensitive environments seen in nuclear power and test reactors, medical isotope production facilities, spent fuel handling, etc. The established choice for high radiation shielding is lead (Pb), which is toxic, heavy, and abidance by RoHS. Concrete, leaded (Pb) bricks are used as construction materials
