The 1990 recommendations of the International Commission on Radiological Protection (ICRP) introduced the concept of the dose constraint and the National Radiological Protection Board response to the recommendations introduced the concept of a generalised derived constraint (GDC).
GDCs have been calculated for discharges to atmosphere, rivers and sewers for the radiologically significant isotopes of hydrogen, carbon, phosphorus, sulphur, chromium, manganese, cobalt, zinc, selenium, technetium, antimony, thorium and neptunium.
