Tritium Surface Contamination

Environmental tritium contamination from a gaseous tritium light device maintenance facility

An investigation was undertaken in relation to the contamination of a facility used for the servicing and refurbishment of gaseous tritium light devices. While it is generally accepted that there is minimal exposure hazard from a broken gaseous tritium light source after the tritium gas has dispersed, environmental tritium contamination displaying ‘particulate’ like characteristics was observed...

Simplified method for detecting tritium contamination in plants and soil.

Cost-effective methods are needed to identify the presence and distribution of tritium near radioactive waste disposal and other contaminated sites. The objectives of this study were to (i) develop a simplified sample preparation method for determining tritium contamination in plants and (ii) determine if plant data could be used as an indicator of soil contamination. The method entailed collec...

Tritium in surface waters of the Yenisei River basin.

This paper reports an investigation of the tritium content in the surface waters of the Yenisei River basin near the Mining and Chemical Combine (MCC). In 2001 the maximum tritium concentration in the Yenisei River did not exceed 4 +/- 1 Bq l(-1), which is consistent with the data of 1998-99. However, it has been found that there are surface waters containing enhanced tritium as compared with t...

Tissue fixation prevents contamination of tritium-sensitive storage phosphor imaging plates.

The use of storage phosphor imaging plates is becoming an increasingly popular alternative to X-ray film when detection speed rather than spatial resolution is the prime concern for detection of radioactive decay during in situ hybridization, northern/Southern blotting and radioligand binding assays. Because the photo-stimulable imaging plates are approximately 5 times more sensitive than tradi...
