DACTARI : DAtabase for Chemical Toxicity and radiotoxicity Assessment of RadIonuclides

Dosimetric impact studies aim at evaluating potential radiological effects of chronic or acute releases from nuclear facilities.

An initial step consisted in identifying and collecting data necessary to apply the methodology, with reference to a previous database of long-lived radionuclides (LLRN, with half-lifes ranging from 30 to 1014 years) containing 95 radionuclides. The initial results have allowed us to identify missing data and revealed the need to complete the study for both toxic and radiotoxic aspects.

The second step consisted in developing a specific database, DACTARI, to collect data on chemical toxicity and radiotoxicity, including acute or chronic toxicity, the chemical form of the compounds, the contamination route (ingestion, inhalation), lethal doses, target organs, intestinal and foetal-maternal transfer, drinking water guidelines, and the mutagenic and carcinogenic properties. This database actually contains 33 radionuclides

When you click on an element from this periodic table, you will obtain specific information on its physico-chemical properties, its acute toxicity and its chronic toxicity.

When you click on one of the 6 results, entitled radiotoxicity, lethal dose, carcinogenicity, ingestion factor, dose coefficients or decorporation you will have access either to a detailed graph or to a coloured table of the 33 elements. -----> see more
