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...

 To the best of our knowledge, imaging of accidental exposure to radioactive fluorine-18 (F-18) due to liquid spill has not been described earlier in the scientific literature. The short half-life of F-18 (t½=110 min), current radiation safety requirements, and Good Manufacturing Practice (GMP) regulations on radiopharmaceuticals have restrained the occurrence of these incidents. The possibilit...

The detonation of an improvised nuclear device or a radioactive dispersal device (RDD) would lead to widespread radioactive contamination, including the potential contamination of individuals. If such an event were to happen, it would be desirable to have various means of rapidly scanning individuals to determine if they have either external or internal contamination and to be able to determine...

Nuclear weapons making and testing, operation of enterprises of the nuclear industry, of military and civilian nuclear fleet, as well as peaceful nuclear explosions – all that led in the USSR to release of radioactive products into the environment. In some parts of the FSU radioactive contamination exceeded permissible levels. The necessity of remediation of such territories became evident. The...

The performance of high-precision mass spectrometry radioactive isotopes can often be hindered by large amounts contamination, including molecular species, stemming from the production beam. In this paper, we report on development Collision-Induced Dissociation (CID) as a means background reduction for experiments at TRIUMF's Ion Trap Atomic and Nuclear science (TITAN). This study was conducted...

Bee products can be contaminated from different sources. The contamination can arise from beekeeping practices or from the environment. Environmental contaminants are covered in the first part of the review. They are: the heavy metals lead, cadmium and mercury, radioactive isotopes, organic pollutants, pesticides (insecticides, fungicides, herbicides and bactericides), pathogenic bacteria and g...
