The National Radiological Protection Board (NRPB) says the UK should adopt international exposure standards. The
NRPB has recommended for many years that nobody should be exposed to a level higher than 1,600 microTeslas. (16
mG)
But in a consultation document on restricting people's exposure, it now recommends the UK should adopt the guidelines
of the International Committee on Non-Ionizing Radiation Protection (Icnirp).
The commission's recommended level is far lower, at 100 microTeslas. (1 mG)
