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 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(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)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). DHS 157.44(7)(7) Radiation surveys. A licensee or registrant shall do all the following: DHS 157.44(7)(a)(a) Conduct all surveys with a calibrated and operable radiation survey instrument that meets the requirements of s. DHS 157.38. 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)(8) Surveillance. During each radiographic operation, the radiographer shall ensure continuous direct visual surveillance of the operation to protect against unauthorized entry into a radiation area or a high radiation area as defined in subchapter I, except at permanent radiographic installations where all entryways are locked and the other requirements of this subchapter are met. DHS 157.44(9)(9) Posting. All areas in which industrial radiography is being performed shall have conspicuous signs posted as required under s. DHS 157.29 (2). The exceptions listed in s. DHS 157.29 (3) do not apply to industrial radiographic operations. DHS 157.44 HistoryHistory: CR 01-108: cr.

A licensee or registrant shall maintain a copy of the license or registration, documents incorporated by reference and amendments to each of these items until superseded by new documents approved by the department or until the department terminates the license or registration. DHS 157.45(2)(2) Records of receipt and transfer of sources of radiation. DHS 157.45(2)(a)(a) A licensee or registrant shall maintain records showing the receipts and transfers of sealed sources, devices using depleted uranium for shielding and radiation machines and retain each record for 3 years after the record is created. DHS 157.45(2)(b)(b) The records shall include the date, the name of the individual making the record, radionuclide, number of becquerels (curies) or mass and manufacturer, model and serial number of each source of radiation and device, as appropriate. DHS 157.45(3)(3) Records of radiation survey instruments. A licensee or registrant shall maintain records of the calibrations of its radiation survey instruments that are required under s. DHS 157.38 and retain each record for 3 years after the record is created. DHS 157.45(4)(4) Records of leak testing of sealed sources and devices containing du. A licensee shall maintain records of leak test results for sealed sources and for devices containing DU. The results shall be stated in units of becquerels or μCi. A licensee shall retain each record for 3 years after the record is made or until the source in storage is removed. DHS 157.45(5)(a)(a) A licensee shall maintain records of the quarterly inventory of sources of radiation, including devices containing depleted uranium as required by s. DHS 157.40 and retain each record for 3 years.
