X-ray and/or gamma emitters in urine
The maximum number of participants for the inter-laboratory comparison is 60.
3 samples of approx. 500 ml (25XGA, 25XGB, 25XGC)
- 1 sample without surcharge
- 2 urine samples overloaded with various X- and/or gamma-emitting radioelements at activity levels less than or equal to 2.00 E+01Bq/L each (excluding 40K). The number of radioelements to be identified and quantified will not be specified.
Stable carriers corresponding to radioelements may have been used in the preparation of urine samples.
This presentation provides a general overview of X-ray and/or gamma-ray intercomparison in urine. The information given here is for guidance only. For official, up-to-date data, please refer to the current year’s interlaboratory comparison campaign plan.
Cadarache is a major nuclear research center where several Installations Nucléaires de Base (INB) and Installations Classées pour la Protection de l''Environnement (ICPE) coexist.
In addition to the biological monitoring of all site staff, the LBM carries out radiotoxicological monitoring of all nuclear industry players working on site (CEA staff, subsidiaries and contractors), as well as certain other organizations under contract to the LABM Cadarache.
In order to apply surveillance adapted to all potential risks of contamination, the examinations carried out by the LBM are very varied:
- Whole-body and urine gamma spectrometry to monitor exposure to fission and/or activation products.
- Lung X-ray spectrometry and urinary and faecal analyses for monitoring actinide exposure.
- Urinary monitoring of exposure to tritium and other beta emitting compounds.
LBM Cadarache is accredited by the French nuclear safety authority (Autorité de Sûreté Nucléaire) for individual monitoring of workers' exposure to ionizing radiation.
