				  removable source stop, "J" tube and collimator when it is used as an exposure
				  head)
Cabinet Radiography
means industrial
				  radiography conducted in an enclosure or cabinet so shielded that doses to

(2) Provide radiation attenuation; and,
(3) Exclude personnel from its interior during generation of
				  x radiation.
Included are all x-ray systems designed primarily for the

				  criteria for x-ray/combination established by CRCPD.
Industrial Radiography
means the
				  examination of the macroscopic structure of materials by nondestructive methods
				  using sources of radiation derived from radioactive materials or radiation
				  machines. For purposes of 105 CMR 120.300, industrial radiography does not
				  include radiography performed with Lixiscopes or cabinet x-ray systems, nor
				  does it include computed tomography or computer-based digital radiography in
