Development of Dose Assessment Code for Accidental Tritium Releases

A computer code ACUTRI has been developed to assess tritium doses to the general public. ACUTRI can calculate the doses for tritium gas (HT) and tritiated water (HTO) accidentally released from the facilities to the atmosphere. The models in this code consist of the tritium transfer model including oxidation of HT to HTO and reemission of HTO from soil to the atmosphere and the dose calculation...

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 Production from Palladium Alloys

A number of palladium alloys have been loaded with deuterium or hydrogen under low energy plasma bombardment in a system that allows the continuous measurement of tritium. Long run times (up to 200 h) result in an integration of the tritium and this, coupled with the high intrinsic sensitivity of the system (~ 0.1nCi/l), enables the significance of the tritium measurement to be many sigma (>10)...
