Public Health England has developed a facility for rapidly monitoring people for internal contamination. For many gamma emitting radionuclides this facility could be used to identify people who require medical assessment and, in the case of intakes of radiocaesium, those who would benefit from decorporation therapy.

This monitoring facility could be quickly deployed to the scene of an incident as comparatively little equipment is required and operation does not require specialist skills.

An evaluation has shown the instrument can detect activities of caesium-137 in people which would result in committed effective doses of less than 1 millisievert assuming default intake parameters for times between intake and screening of up to 14 days.
