The code applies to all persons who are exposed to ionising radiations arising
from dental practice and there are thirteen such persons employed by the council.
As the overall rate of radiation exposure is low our dental staff have not been
designated as radiation workers and individual four-weekly film tests made every
six months have ensured that operating conditions remain satisfactory.
GAS LASERS
It is understood that the Department of Education and Science is preparing a
Code of Practice for the use of laser light in schools. The main safety factor will
be to keep the power output very low, below 0.5 milliwatts. The output of the
laser should not be viewed even when reflected without diffusing it in some way,
nor should the beam be allowed to fall on any part of the body.
A gas laser has been purchased by Winchmore School.
