The Code of Practice applies to the use of ionising radiations arising from
X-ray machines in the Council's dental clinics. There are eight clinics using X-ray
machines and approximately 1,433 X-ray exposures were taken : 1,298 were for
orthodontic purposes and the remainder were taken during the course of general
dental treatment. A total of 592 pupils had an X-ray examination.
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.
During the year, another school, St. Ignatius College, purchased a gas laser.
