According to Section .1604, Chapter 11 of Title 15A of the North Carolina Administrative Code, the exposure limits for adults are as follows:
1) an annual limit, which is the more limiting of: (A) the total effective dose equivalent being equal to five rems (0.05 Sv); or (B) the sum of deep-dose equivalent and the committed dose equivalent to any individual organ or tissue other than the lens of the eye being equal 50 rems (0.5 Sv); and 2) the annual limits to the lens of the eye, to the skin, and to the extreminities which are: (A) an eye dose equivalent of 15 rems (0.15 Sv), and (B) a shallow-dose equivalent of 50 rems (0.50 Sv) to the skin or to each of the extreminities.
The X-ray Structural Facility keeps copies of excerpts of the North Carolina Regulations for Protection Against Radiation (the yellow covered copy) and Handbook for Protection Against Ionizing Radiation (gray covered booklet). Authorized users of the Facility are responsible for reading all of the yellow covered photocopy and the sections pertaining to devices which produce ionizing radiation as part of their training. The Facility copies of these materials are located where the Facility's Safety Plan is located. Additional copies may be obtained by contacting Radiation Protection Services (5-2894).
None, however this is the most appropriate place to mention general safety. Common sense is your greatest piece of personal protective equipment. When you enter the laboratory, note which diffractometers are generating X-rays. This is indicated by the large red light on top of the tube shield located near where the HV cable comes out of the tube shield. The shutter open (2 red) indicator lights are also located on top of the tube shield near the collimator. Never open the radiation safety enclosure when an experiment is in progress.
Normal operation of the equipment never requires exposure to X-ray generator. Therefore, never open the back of the generator. Only qualified repair technicians and the authorized user in charge are authorized to do this, and only when the repair or maintenance of the equipment requires it.
