25 Pa. Code § 225.71. Definitions.


§ 225.71. Definitions.

 The following words and terms, when used in this subchapter, have the following meanings, unless the context clearly indicates otherwise:

   DRD—Direct reading dosimeter

     (i)   As used in this subchapter, means an ‘‘individual monitoring device’’ (see 10 CFR 20.1003 (relating to definitions)) that does not require additional processing to measure an individual’s dose.

     (ii)   The term also includes the direct reading personnel (individual) monitoring devices known as pocket dosimeter, pocket ionization chamber and electronic personal dosimeter (EPD).

   Field radiography—A location where radiographic operations are conducted (onsite or offsite) other than those designated as a permanent radiographic facility.

   Industrial radiography—An examination of the structure of materials by nondestructive methods, utilizing ionizing radiation to make radiographic images.

   NVLAP—National Voluntary Laboratory Accreditation Program.

   Personal supervision—The provision of guidance and instruction to a radiographer’s assistant given by a radiographer who is:

     (i)   Physically present at the site.

     (ii)   In visual contact with the radiographer’s assistant while the assistant is using radiation sources.

     (iii)   In proximity so that immediate assistance can be given if required.

   Personnel dosimeter—As used in this subchapter, means any of the ‘‘individual monitoring devices’’ (see 10 CFR 20.1003) that shall be processed and evaluated to generate a permanent record of an individual’s dose, for example, a film badge, thermoluminescent dosimeter (TLD) or optically stimulated luminescent dosimeter (OSLD).

   RSO—radiation safety officer—An individual who ensures that, in the daily operation of the registrant’s or licensee’s radiation safety program, activities are being performed in accordance with approved procedures and are in compliance with Department requirements.

   Radiographer—An individual who performs radiographic operations or an individual in attendance at a site where radiation-producing devices are being used who personally supervises industrial radiographic operations.

   Radiographer’s assistant—An individual who, under the personal supervision of a radiographer, uses radiation-producing devices or radiation survey instrumentation.

   Radiographic operations—The activities associated with a radiation-producing device during use of the device, to include surveys to confirm adequacy of boundaries, setting up equipment and any activity inside restricted area boundaries.

   Radiographic X-ray system—A system utilizing a radiation generating device for quality assurance, materials detection or nondestructive testing used in industrial settings.

   Safety device—As applied to radiation-producing devices in this subchapter, a device or component that causes the unit to de-energize or interrupt the beam.


   The provisions of this §  225.71 amended July 16, 2004, effective July 17, 2004, 34 Pa.B. 3823; amended August 11, 2023, effective 90 days after publication, 53 Pa.B. 4977. Immediately preceeding text appears at serial pages (304540) to (304541).
