25 Pa. Code § 225.103. Field radiography.

§ 225.103. Field radiography.

 (a)  The operator shall conduct a physical radiation survey to determine that the radiation source is de-energized prior to each entry into the radiographic exposure area. Survey results and records of the boundary location shall be maintained and kept available for inspection by the Department for 5 years.

 (a.1)  Surveillance of the exposure area shall be maintained during operation, either by visual or by other reliable means, to ensure that no person enters the area.

 (a.2)  With the exception of hand-held X-ray systems, when approaching the radiation source, following the conclusion of an exposure, the operator shall use a suitable calibrated and operable radiation detection instrument to verify that the radiation source is in its fully shielded condition or that the X-ray tube has been de-energized.

 (a.3)  A personal alarming dose rate meter shall also be worn to approach the work area if the device is appropriately designed and calibrated for the type of X-ray emitted, either pulse or continuous, set at an appropriate level to detect the presence of the source, for example 2 mrem (0.02 mSv) per hour and has been source-checked prior to use. The radiation in the work area must be reasonably uniform so that the device responds to radiation exposure to any part of the body. It may not be used to measure radiation levels, nor may it be used to indicate the presence of the source for potential non-uniform exposure, such as may occur during device maintenance or work in a radiation-producing device target area.

 (a.4)  Measurement of radiation levels for a radiation survey shall be performed using an appropriately calibrated radiation survey meter. A radiation survey meter shall also be used when there is potential for non-uniform exposure to personnel, such as may occur during device maintenance or work in a radiation-producing device target area.

 (a.5)  During the initial exposure, the radiation levels shall be measured around the perimeter of the controlled area. The perimeter shall be adjusted accordingly to meet the access control requirement for radiation areas or high radiation areas.

 (a.6)  The survey around the perimeter shall be made for each new operating condition and the perimeter adjusted accordingly.

 (b)  Mobile or portable radiation-producing devices shall be physically secured to prevent tampering or removal by unauthorized personnel.
