Current through Register Vol. 54, No. 7, April 4, 2022
person shall operate or permit the operation of any ionizing
radiation-producing machine used in shielded room radiography unless the
equipment, installation, and personnel meet the requirements of
through 17.6 and this
No person shall
operate or permit any person to operate an ionizing radiation-producing machine
used in shielded room radiography until such operator has completed the
The operator has
met the requirements of
The operator has received a copy of and
instruction in N.J.A.C. 7:28-1 through 7:28-13 and 7:28-17 and a copy of the
owner's operating and emergency procedures as required by
has demonstrated an understanding of the procedures and regulations by written
examination given by a qualified individual; and
3. The operator has demonstrated competence
to operate appropriate safety systems.
(c) Each owner shall supply appropriate
personnel monitoring equipment and shall require that it be used by every
individual who operates, makes "set-ups," or performs maintenance on an
ionizing radiation-producing machine used in shielded room
(d) The enclosed room
in which shielded room radiography is conducted shall be shielded so that no
location on the exterior exceeds the radiation levels and limits established in
N.J.A.C. 7:28-6. No industrial radiography shall be conducted in a shielded
room until a radiation survey is first made to insure compliance with these
radiation levels and limits. A record of this survey shall be maintained and a
copy shall be available for inspection by the Department.
(e) No person shall enter an enclosed room in
which shielded room radiography is performed until after a physical radiation
survey is conducted to determine whether the ionizing radiation producing
machine is off. A record shall be maintained of the date and exposure rate
measured for each physical radiation survey and shall be made available for
inspection by the Department.
The radiation surveys required in (d) and (e) above shall be made with a
radiation survey instrument measuring radiation at the energies and at the
exposure rates to be encountered. This instrument shall have an operational
check source test conducted prior to each use and shall be calibrated at
intervals not to exceed one year and shall be recalibrated after each servicing
other than a battery replacement. Records shall be maintained of each date of
calibration and the daily operational check and shall be made available for
inspection by the Department.
Adequate methods shall be provided to restrict the access of personnel and the
public to any and all shielded room radiography areas to prevent the exposure
of any person to radiation in excess of the level limits of N.J.A.C. 7:28-5,
7:28-6 and 7:28-17. No person is permitted to remain within the enclosed room
where shielded room radiography is being performed.
All ionizing radiation-producing machines
used in shielded room radiography and all objects exposed thereto shall be
confined within an installation or structure designed or intended for
radiography and in which radiography is regularly performed in accordance with
the following requirements:
1. A reliable
interlock or other mechanism shall be installed at each means of access to the
shielded room which will turn off the source(s) of radiation if a person tries
to enter or open the door to the shielded room.
2. A door-fastening mechanism shall be
installed so that the door to the shielded room can be opened from the inside
at all times in case of emergency.
3. A visible and audible signal alarm system
shall be installed within the shielded room which will be actuated at a
reasonable length of time before the power to the radiation source can be
activated which enables persons in the vicinity of the shielded room to take
appropriate protective actions.
One or more scram or emergency buttons shall be installed at a highly visible
and easily accessible location or locations within the shielded room that will
terminate the power to the source of radiation. This scram or emergency button
shall be installed so that it shall require manual resetting before the power
to the source of radiation can be reactivated.
5. Each source of radiation used in shielded
room radiography shall be provided with a lock at the control panel to prevent
unauthorized use of the source.
If more than one source of radiation is used in the same shielded room, all
such sources of radiation shall meet the requirements of 1-5 above.
