International Standards Organization assessment, 14040 series

The assessment analysis is a long and complex process that follows the procedures established through the International Standards Organization (ISO) through its 14000 series set of standards. The ISO 14000 delineates a series of steps that includes ... 

The Guidelines for Drinking-Water Quality published by the World Health Organization (WHO) is the key international reference point for standard setting and drinking water safety. The WHO has developed a series of guidelines that present an assessment of the health risks associated with exposure to health hazards through water The information is essential to assist water suppliers to implement their own safe water acts. 

In another study carried out at a different nuclear establishment, the isotopes and were determined (along with calculated concentrations) in a series of human urine samples, using a concentrated aqua regia wet oxidation method to dissolve the uranium and destroy the organic matter. The uranium was selectively separated from the matrix using anion exchange, eluted with dilute nitric acid, and then aspirated into the ICP mass spectrometer. Using this method, a detection limit of 6 ng/L was achieved, with excellent spike recoveries at the 200 ng/L level, which met both plant and industry standard (American National Standards Institute 13.30) internal dose assessments for total uranium. ...
