NRPB Levels in Amateur Bands Reduced

The Reference Levels for UK Amateur Radio Bands, published by the National Radiological Protection Board (NRPB), were reduced at the end of July this year.

These set the level, above which more detailed calculations and checks should be performed, to ensure safe human exposure limits are not exceeded. The lowest levels applying to HF and VHF bands have reduced from 50V/m to 28V/m.

This topic is covered in the syllabus of the Radio Communications Examination Advanced examination. Due to the change, questions will not be asked on the numerical values until all tutors have been informed and have had an opportunity to inform their students. The next advanced exam is on Tuesday 26 October.
