A radiation attenuation corridor couples a radiation therapy room and a control room. The radiation attenuation corridor is made of a material that substantially absorbs ionizing radiation and substantially blocks the transmission of the ionizing radiation. Specific wall portions at the entrance of the corridor are covered with borated polyethylene (BPE). Specific wall portions diverge from an axis defined by the corridor by from about 10 degrees to about 45 degrees. The corridor thus leads out ...

The present invention relates to an immobilizing medium for the encapsulation of radioactive waste. The waste immobilizing medium has a sodium silicate based glass matrix in which there is contained radioactive waste wherein the waste comprises one or more inert metal components and one or more fission products. At least a portion of the inert metal components are dissolved in the glass matrix and increase its durability. As a result, the waste immobilising medium is highly durable and leach res...

A method and apparatus for transporting radiopharmaceuticals. Typically, the apparatus is a two-part assembly, each part having an exterior shell, a radiation shield and a non-porous lining. Additionally, the assembled apparatus has a sealed internal chamber suitable for carrying a syringe or a sharps container containing a syringe. The internal chamber of the radiopharmaceutical pig is lined with a non-porous lining, typically a durable plastic, that prevents contamination of the radiopharmaceu...

The invention related to a radiation protection arrangement for screening radiation emitted from a radiation source, especially an x-ray source. Said arrangement is provided with a screening element consisting of, or comprising, a radiation protection material, and a cover, which fully surrounds the screening element. Said cover can be pulled over the screening element and completely separated from the same. As the cover can be changed, the radiation protection arrangement can be kept clean and ...

A radiation attenuation system suitable for use in radiological examinations includes a first portion comprising a radiation attenuation material and a second portion comprising a relatively non-radiation attenuation buffer region between the radiation attenuation material and an article undergoing the examination. The radiation attenuation system may be positioned over, under, near, or otherwise about the article. According to one embodiment, the radiation attenuation system is intended to be p...

A method (and concomitant kit) for treating a surface to reduce subsequent .sup.137Cs nuclide desorption comprising contacting the surface with a first cation-containing solution, the cation being one or more of Cs.sup.+, Rb.sup.+, Ag.sup.+, Tl.sup.+, K.sup.+, and NH.sub.4.sup.+, and contacting the surface with a second cation-containing solution, the cation being one or more of Cs.sup.+, Rb.sup.+, Ag.sup.+, Tl.sup.+, K.sup.+, and NH.sub.4.sup.+, thereby reducing amounts of radioactive cesium em...

A radiation protection system for shielding medical personnel from a gamma ray source being used to provide brachytherapy to a patient is provided by disposing shielding material between the source of radiation and locations outside the radiation protection system in such a manner as to provide shielding for the primary radiation in directions from which radiation from the source may emerge, while providing the patient an open viewing area with a large field of view for the patient to view the l...

The invention relates to a container (1) intended for transport/storage of radioactive materials, the container comprising a container body (2) and at least one handling device (8) mounted using attachment screws (38) in a base housing (30) delimited by a base housing wall (32). According to the invention, a sealing plate (50) covering the attachment screws is installed removably in a plate housing (52) delimited by a plate housing wall (56) provided on the handling device and by a portion (58) ...

An elastic, radiation shielding material that can be severed readily with conventional tools, such as scissors and is sufficiently flexible so as to allow wrapping it around piping and tubing. The radiation shielding material comprises a rubber component and a radiation attenuating metal in amounts effective to obtain a desired balance of flexibility and radiation attenuation, respectively. By varying the amount of rubber and metal in the material a desired level of flexibility and radiation att...

A method and apparatus for treating radioactive waste water containing contaminating ions, colloids and suspended solids having like (usually negative) charges preventing their precipitation. An electric current is passed through the waste water in an EC assembly to cause electro-coagulation of the contaminants and anodes of this assembly are made of a metal that dissolves to provide cations for neutralizing the negative charges and forming precipitates containing neutralized contaminants. Preci...
