DHS 157.44(5)(a)
(a) A radiographer's assistant shall be personally supervised by a radiographer when the assistant is using radiographic exposure devices, associated equipment or a sealed source or while conducting radiation surveys required by sub.
(7) (b) to determine that the sealed source has returned to the shielded position or the radiation machine is off after an exposure. The personal supervision shall include all the following:
DHS 157.44(5)(a)1.
1. The radiographer's physical presence at the site where the sources of radiation are being used.
DHS 157.44(5)(a)2.
2. The availability of the radiographer to give immediate assistance if required.

3. The radiographer's direct observation of the assistant's performance of the operations referred to in this section.
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. 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. Dosimeters shall comply with all of the following conditions:
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. Film badges shall be replaced at least monthly and all other personnel dosimeters that require replacement must be replaced at least quarterly. All personnel dosimeters must be evaluated at least quarterly or promptly after replacement, whichever is more frequent.
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.

(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 found to be off-scale, or if the electronic personal dosimeter reads greater than 2 millisieverts (200 mrem), and the possibility of radiation exposure cannot be ruled out as the cause, the personnel dosimeter that requires processing shall be sent for processing and evaluation within 24 hours. If a personnel dosimeter does not require processing, evaluation of the dosimeter shall be started 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 dose 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)(g)
(g) Each alarming ratemeter shall meet all the following criteria:

DHS 157.44(7)(b)
(b) Conduct a survey of the radiographic exposure device and the guide tube after each exposure when approaching the device or the guide tube. The survey shall determine that the sealed source has returned to its shielded position before exchanging films, repositioning the exposure head or dismantling equipment. 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.
DHS 157.44(8)
