The Programs We Offer

The National Calibration Reference Centre for Bioassay and In Vivo monitoring (NCRC) offers two main programs each of which provides several services:

1. The Bioassay intercomparison program is concerned with the calibration of measurements for radioactive isotopes in human urine samples. This program offers intercomparison samples for measurement of the following materials in urine:
   
   
   1. Uranium
   2. Tritium
   3. Carbon-14
   4. Tritium and Carbon-14
   5. Fission and Activation Products
      
      
2. The In Vivo Monitoring intercomparison program is concerned with the calibration of measurement for radioactive isotopes directly in the human body. Phantoms or mannequins shaped to resemble parts of the human body are prepared which contain known quantities of radioactivity. Three programs are offered:
   
   
   1. Thyroid
   2. Lung
   3. Whole Body
