Summary

How operators of nuclear sites in England and Wales should design and carry out an environmental radiological monitoring programme as required by a radioactive substances activity permit. This guidance is also for regulators and other organisations who have, or participate in, independent environmental radiological monitoring programmes.

This guidance is mainly for designing new programmes, or reviewing existing programmes, around nuclear licenced sites to monitor the effects of permitted discharges.

It is to help you:

  • define an objectives based environmental monitoring programme
  • determine what to monitor, where and how often
  • choose your main monitoring and sampling techniques

By using this guidance, you will be able to support demonstration that your radiological environmental monitoring programmes are using best available techniques (BAT).

This guidance replaces the previous version, Radiological monitoring technical guidance note 2: environmental radiological monitoring.
