Abstract
The invention relates to a method of estimating the tritium dose absorbed by a person exposed to an environment with a tritium atmosphere. Applications of the invention include particularly dosimetric monitoring of tritium in persons exposed to an environment containing a significant amount of tritium during their activities, as is the case for the nuclear industry.
Claims3
Method for estimating the tritium dose (expressed in Sieverts (Sv)) absorbed by a person after exposure of said person to a tritiated environment for a duration τ (expressed in hours(h), said method comprising the following steps:
- a) a step to measure the activity per unit volume of tritium present in said environment (denoted CHTO and expressed in Becquerels per litre (Bq/L));
- b) a step to estimate the dose absorbed by said person, using the following relation:
- Dose=CHTO×τ×DPUIHTO×1800,
- in which:
- CHTO is the activity per unit volume of tritium (expressed in Becquerels per litre (Bq/1)) measured in the previous step a);
- and
- DPUIHTO is equal to 1.8×10−11 Sieverts per Becquerel (Sv/Bq).
