DHS 157.44(6) (6)Personnel monitoring.
DHS 157.44(6)(a)(a) A licensee or registrant may not permit any individual to act as a radiographer or a radiographer's assistant unless, at all times during radiographic operations, each individual wears on the trunk of his or her body a combination of direct reading dosimeter, an alarming ratemeter and a personnel dosimeter that is processed and evaluated by an accredited National Voluntary Laboratory Accreditation Program processor. At permanent radiographic installations where other appropriate alarming or warning devices are in routine use or during radiographic operations using radiation machines, the use of an alarming ratemeter is not required.
DHS 157.44(6)(a)1. 1. Pocket dosimeters shall have a range from zero to 2 millisieverts (200 mrem) and shall be recharged at the start of each shift. Electronic personal dosimeters may only be used in place of ion-chamber pocket dosimeters.
DHS 157.44(6)(a)2. 2. Each personnel dosimeter shall be assigned to and worn by only one individual.
DHS 157.44(6)(a)3. 3. Personnel dosimeters shall be exchanged at periods not to exceed one month.
DHS 157.44(6)(a)4. 4. After replacement, each personnel dosimeter shall be processed according to NVLAP approved procedures, or shall be returned to the supplier for processing within 14 calendar days of the end of the monitoring period or as soon as practicable. In circumstances that make it impossible to return each personnel dosimeter within 14 calendar days, the circumstances shall be documented and available for review by the department.
DHS 157.44(6)(b) (b) Direct reading dosimeters such as pocket dosimeters or electronic personal dosimeters, shall be read and the exposures recorded at the beginning and end of each shift and records shall be maintained as specified under s. DHS 157.45 (11)
DHS 157.44(6)(c) (c) Pocket dosimeters or electronic personal dosimeters shall be checked at periods not to exceed 12 months for correct response to radiation and records shall be maintained as specified under s. DHS 157.45 (11). Acceptable dosimeters shall read within plus or minus 20% of the true radiation exposure.
DHS 157.44(6)(d) (d) If an individual's pocket dosimeter is determined to be off-scale or the electronic personal dosimeter reads greater than 2 millisieverts (200 mrem), the individual's film badge, TLD or similar approved device shall be sent for processing within 24 hours. In addition, the individual may not resume work associated with the use of sources of radiation until a determination of the individual's radiation exposure has been made. The determination shall be made by the radiation safety officer or the radiation safety officer's designee. The results of the determination shall be included in the records maintained under s. DHS 157.45 (11).
DHS 157.44(6)(e) (e) If a personnel dosimeter is lost or damaged, the worker shall cease work immediately until a replacement personnel dosimeter is provided and the exposure is calculated for the time period from issuance to loss or damage. The results of the calculated exposure and the time period for which the personnel dosimeter was lost or damaged shall be included in the records maintained as specified under s. DHS 157.45 (11).
DHS 157.44(6)(f) (f) Dosimetry reports received from the accredited National Voluntary Laboratory Accreditation Program personnel dosimeter processor shall be retained as specified under s. DHS 157.45 (11).
DHS 157.44(6)(g) (g) Each alarming ratemeter shall meet all the following criteria:
DHS 157.44(6)(g)1. 1. Checked to ensure that the alarm functions properly before using at the start of each shift.
DHS 157.44(6)(g)2. 2. Set to give an alarm signal at a preset dose rate of 5 millisieverts (500 mrem) per hour; with an accuracy of plus or minus 20% of the true radiation dose rate.
DHS 157.44(6)(g)3. 3. Require special means to change the preset alarm function.
DHS 157.44(6)(g)4. 4. Calibrated at periods not to exceed 12 months for correct response to radiation. A licensee shall maintain records of alarming ratemeter calibrations as specified under s. DHS 157.45 (11).

Radiation machines shall be surveyed after each exposure to determine that the machine is off.
DHS 157.44(7)(c) (c) Conduct a survey of the radiographic exposure device whenever the source is exchanged and whenever a radiographic exposure device is placed in a storage area to ensure that the sealed source is in its shielded position.
