Section R. 325.5222 - Personnel monitoring

Rule 222.

(1) Each licensee or registrant shall supply appropriate personnel monitoring equipment to, shall require the use of such equipment by, and shall demonstrate compliance pursuant to this rule for the following:

(a) Each individual under such circumstances that he or she receives, or is likely to receive, a dose in any calendar quarter in excess of 25% of the quarterly occupational limit specified in Rule 205, (e.g. 300 mrems whole body).

(b) Each individual under 18 years of age under such circumstances that he or she receives, or is likely to receive, a dose in any calendar quarter in excess of 5% of the quarterly occupational limit specified in Rule 205, (e.g. 60 mrems whole body).

(c) Each individual, except a patient being intentionally irradiated, who enters a high radiation area.

(d) Each individual who is likely to receive a dose in excess of 100 millirems in any 5 consecutive days while in a room or area occupied by a patient while the patient is receiving therapy from any gamma-emitting radioactive material.

(e) Each individual for whom personnel monitoring is specifically required under other parts of these rules pertaining to specific uses of sources of radiation.

(2) Monitoring devices used to estimate whole body exposure shall normally be worn on the chest or abdomen. The dosimeter assigned for monitoring the trunk of the body shall not be used for any other purposes. If monitoring of other areas of the body (e.g. lens of the eye, extremity) is required by these rules or requested by the radiation worker because of the nature of exposure, a separate dosimeter shall be assigned for this purpose. The separate dosimeter shall be designated as an auxiliary dosimeter and the radiation record shall specify the specific area monitored.

(3) If auxiliary dosimeters are assigned in accordance with subrule (2) of this rule, the specific body area shall be monitored for a minimum 13 consecutive weeks. If this monitoring results in recorded exposures in excess of 25% of the applicable specified quarterly limit in Rule 205 (e.g. 300 mrems lens of the eye, 6.25 rems hands), the auxiliary dosimeter shall be permanently assigned to monitor that area.
