Determining the content of transuranium elements, Americium (Am), Plutonium (Pu), Neptunium (Np), and Curium (Cm) in the nuclear fuel cycle and in nuclear radioactive waste is important for both economic and human toxicity reasons. The major concern is processing the sample rapidly and quantitating these transuranium alpha emitters in the presence of 10 fold excess of beta emitting contaminants...

Background: The formalism recommended by Task Group 60 (TG-60) of the American Association of Physicists in Medicine (AAPM) is applicable for β sources. Radioactive biocompatible and biodegradable 153Sm glass seed without encapsulation is a β- emitter with a short half life and delivers a high dose rate to the tumor in the millimeter range. In this work the dosimetry parameters of the ...

The results of research on the application method measurement gross alpha-, beta-activity in water using liquid scintillation counter (LSC) Quantulus 1220 are presented. Basic procedures preparation and spectrometric aqueous samples were studied performed. detection efficiency beta-particles depending quenching optimum beta-radiation separation parameter for used determined. Testing validation ...

A new method has been developed to image surface contamination on-site by short range radiation emitters (such as alpha or beta particle emitters). The measurement is performed in direct contact with the contaminated and uses a solid scintillator coupled Silicon Photomultiplier arrays. proof of principle laboratory using simple prototype multiple calibrated sources. experimental setup used acqu...
