1 Scope
This International Standard specifies the minimum requirements for the design of professional
programmes to monitor workers exposed to uranium compounds. It establishes principles
for the development of compatible goals and requirements for monitoring programmes and dose assessment for workers occupationally exposed to internal contamination . It establishes procedures and assumptions for risk analysis, monitoring programmes and the standardised interpretation of monitoring data in order to achieve acceptable levels of reliability for uranium and its compounds.
It sets limits for the applicability of the procedures in respect to dose levels above
which more sophisticated methods have to be applied.
Uranium is both radiologically and chemically toxic. Hence, the scientific bases of
current occupational exposure standards are reviewed in addition to radiation exposure
limits. This International Standard addresses those circumstances when exposure could
be constrained by either radiological or chemical toxicity concerns.
This International Standard addresses, for uranium and its compounds, the following
items:
a) purposes of monitoring and monitoring programmes;
b) description of the different categories of monitoring programmes;
