(7) Information regarding a woman's condition under subsections (5) and (6) shall be noted on the requisition before the examination is done and shall be kept on file with the patient's records.
Review of regulations
21. The Radiation Health and Safety Advisory Committee shall review these regulations periodically and make those recommendations to the minister that are indicated by the review.
Category 1 - Female radiation workers not known to be pregnant but in the child-bearing years.
Category 2 - Female radiation workers known to be pregnant.
Category 3 - All other radiation workers.
NOTE: Where a radiation worker is also an 'atomic energy worker' as defined in the Atomic Energy Control Regulations (Canada), the maximum combined permissible dose accumulation from ionizing radiation and from other radiations having a similar effect on the body can be read from this Schedule on substitution of the word "rems" for the word "rads".
