Ceramic Radiation Shielding Material

As we experienced difficulties during the reconstruction of the concrete shielding wall of the linac room brick type of shielding material which can be fast assembled in situ with a flexibility to be shaped any form was expected to replace.

Ceramic radiation shielding material. Mtaika mori abelia ocn ne jp 2 ofuna chuo hospital kamakura 247 0056 japan. Glasses have many advantages such as high optical transparency ease of preparation in different ways ease in formatting and low cost 6 7 8. The use of radiation in diagnosing and treating patients has significantly advanced the field of medicine and saved or extended countless lives advances in technology and more sophisticated applications have improved standard treatments for the benefit of the patient. A composition of matter and method of forming a radiation shielding member at ambient temperatures in which the composition of matter includes a cold fired chemically bonded oxide phosphate ceramic cement matrix.

In this study we developed a new ceramic material with a high shielding capacity against the high energy gamma radiation from 137 cs and 60 co sources. In 2005 silflex tungsten shielding was developed and certified by entergy and ano in 2007 for use in the nuclear industry. In the present work eight types of ceramic materials have been used as a shielding material and tested against gamma ray each type of ceramic modified as glazed and unglazed. One of these ways is shielding.

The radiation sources 137cs and 60co were used to calculate attenuation. Ceramics article iron iii oxide based ceramic material for radiation shielding hiroyuki mori 1 yohei oku 2 yudo mannami 1 and takahiro kunisada 3 1 mitsuishi refractory brick co ltd 868 mitsuishi bizen shi okayama 705 0132 japan. Radiation shielding is imperative as radiation can be a serious concern in nuclear power facilities industrial or medical x ray systems radioisotope projects particle accelerator work and a number of other circumstances. This is a long list of properties for one material.

Radiation shielding materials are used for a variety of radiologic applications. With one or more suitably prepared and distributed radiation shielding materials dispersed in the cold fired chemically bonded oxide phosphate ceramic cement matrix. American ceramic technology inc. These materials have good radiation shielding factors but have many problems such as being opaque to visible light and only be suited to limited numbers of applications.

Therefore it is common to design multiple layers of shielding structures.
