This paper describes the utility of the electrochemical technique for the preparation of a
circular planar 204Tl source required for the calibration of beta surface contamination …

A method is described for the preparation of standard radioactive sources for routine
calibration of β-surface contamination monitors. 90 Sr+ 90 Y electrodeposited reference …

[en] This instrument is a well designed, well constructed contamination monitor that has
unusual versatility. Where large surface areas require to be monitored it is particularly useful …

An anodically oxidised layer of aluminium was found to be a satisfactory substrate for
holding millicurie amounts of carrier-free 147 Pm activity, which is used as a source of beta …

ABSTRACT—...————A Kanne chamber has been redesigned to reduce its sensitivity to
such contaminants az tritium water vapor fir.! triti (ltedoil. The high voltage electrode has …

The present volume and its companion Volume 2 document the proceedings of the
Symposium on Surface Contamination: Its Genesis, Detection and Control held in …

Abstract Nuclear Track Detectors (NTD's) are used as passive systems to detect the alpha
contamination on flat or semirough surfaces. The procedure for the application of these …

This study was a material compatibility assessment of four metals (beryllium, stainless
uranium, 304L stainless steel, and 2024-T3 aluminum) with an environmentally benign, non …

A tritium calibration source is described in which there is no self absorption, therefore, the
Beta Emission spectrum is not distorted other than by backscatter. The source consists of an …

The evaporation rates of barium and calcium from impregnated tungsten dispenser
cathodes have been determined by both a vapor-collect method and line-of-sight mass …
