Section 20.3.5.26 - SPECIAL REQUIREMENTS FOR RADIOGRAPHY EMPLOYING RADIATION MACHINES

A. Shielded Room Radiography. Shielded room radiography (as defined in Subsection AK of 20.3.5.7 NMAC) using radiation machines shall be exempt from other requirements of this Part; however:

(1) no registrant shall permit any individual to operate a radiation machine for shielded room radiography until such individual has received a copy of, and instruction in, and demonstrated an understanding of operating procedures of the unit, and has demonstrated competence in its use;

(2) each registrant shall supply appropriate personnel monitoring equipment to, and shall require the use of such equipment by, every individual who operates, makes "set-ups", or performs maintenance on a radiation machine for shielded room radiography; and

(3) a physical radiation survey shall be conducted to determine that the radiation machine is "off" prior to each entry into the shielded room. Such surveys shall be made with a radiation measuring instrument which is capable of measuring radiation of the energies and at the exposure rates to be encountered, which is in good working order, and which has been properly calibrated within the preceding three months or following the last instrument servicing, whichever is later.

B. Other Radiography Using Radiation Machines. Other radiography using machines shall be exempt from 20.3.5.17 NMAC, 20.3.5.21 NMAC, 20.3.5.22 NMAC, and 20.3.5.24 NMAC; however:

(1) A physical radiation survey shall be conducted to determine that the radiation machine is "off" prior to each entry into the radiographic exposure area. Such surveys shall be made with a radiation measuring instrument capable of measuring radiation of the energies and at the exposure rates to be encountered, which is in good working order, and which has been properly calibrated within the preceding three months or following the last instrument servicing, whichever is later. Survey results and records of boundary locations shall be maintained and kept available for inspection; and

(2) Mobile or portable radiation machines shall be physically secured to prevent removal by unauthorized personnel.
