Swipe assays are routinely performed in laboratories and other facilities that use or handle radioactive materials. These assays, often referred to as smear or wipe tests, are performed to comply with radioactive material license requirements, assure laboratory safety, and provide information that proper handling procedures are being followed. Typically, swipes are performed to monitor for the ...

The decomposition of radioactive chemical products usually follows an exponential dynamics. The present paper deals with the problem of analyzing the unknown dynamics of pseudo radioactive materials for which we have a temporal sample of the amount of the decomposing product. The strategy for studying if the adjustment of the dynamics is or not of exponential type is to use a recent generalizat...

Feasibility tests were initiated to determine if the zirconium in commercial used nuclear fuel (UNF) cladding can be recovered in sufficient purity to permit re-use, and if the recovery process can be operated economically. Initial tests are being performed with unirradiated, non-radioactive samples of various types of Zircaloy materials that are used in UNF cladding to develop the recovery pro...

The Hazardous Material Removal Program will provide all academic departments and faculty with the opportunity to dispose of unneeded hazardous chemicals and radioactive material with no EH&S recharge. The disposal program will be organized building by building and advanced notice will be given to each department. Radioactive waste and materials along with routine chemical waste will be collecte...

Gas chromatographs equipped with electron capture detectors (ECD) are widely used for the analysis of electron affine substances. Achieving limits of detection in the low pptv-range, electron capture detectors are the most sensitive detectors available for such compounds. Based on their operating principle, they require free electrons at atmospheric pressure, which are usually generated by usin...

Naturally Occurring Radioactive Materials, often referred to by the acronym NORM, are and always have been a part of our world. Our planet and its atmosphere contain many different naturally occurring radioactive species, and it and virtually everything, living or inanimate, contains NORM. In the history of mankind, knowledge of the existence of radioactivity is very recent, even when considere...

A coordinated research project initiated by the IAEA on “Radiochemical, chemical and physical characterization of radioactive particles in the environment” was conducted by a research group representing twelve countries (Brazil, Denmark, Finland, Hungary, Israel, Kazakhstan, Norway, Russian Federation, Spain, Ukraine, USA) and the European Commission Joint Research Centre Institute for Transura...

The maximum allowable biological concentration of a toxic substance is the highest concentration which can be found in a biological medium without damage to health. The biological materials rna y be examined for: (a) the toxic substance itself; (b) a product of the metabolism of the toxic substance in the body; (c) a substance derived from the physiopathological activity of the toxic substance;...
