Current through Register Vol. 56, No. 24, December 18, 2024
(a)
Electron microscopes shall be exempt from the requirements of
N.J.A.C.
7:28-20.4 through
N.J.A.C.
7:28-20.12 except for the following
requirements:
1. The registrant shall not use
or cause an electron microscope to be used unless a radiation protection survey
has been performed by an individual under the supervision of the PASO as
defined in N.J.A.C. 7:28-20.4 to ensure
compliance with N.J.A.C. 7:28-5 and 7 before the electron microscope is put
into operation; the registrant shall submit a copy of the survey report to the
Department within 30 days of the date of the survey and shall maintain the
original survey report at the electron microscope facility; the survey report
shall be produced for review by the Department during an inspection;
2. The electron microscope shall be be
resurveyed after every repair, modification, or relocation that would affect
radiation exposure; the registrant shall submit a copy of the survey report to
the Department within 30 days of the date of the resurvey and shall maintain
the resurvey report at the electron microscope facility; the resurvey shall be
produced for review by the Department during an inspection;
3. The registrant shall ensure that the
electron microscope operating parameter indicators and controls pertinent to
the production of radiation are clearly identified and easily discernible; the
electron microscope shall be provided with a clearly visible label bearing the
conventional radiation symbol and the words CAUTION: THIS EQUIPMENT PRODUCES
X-RAYS WHEN ENERGIZED or other words having equivalent meaning affixed on the
column;
4. The registrant shall
provide each electron microscope operator with appropriate personnel monitoring
equipment as required by N.J.A.C. 7:28-7 and require that the device be worn by

from the personnel monitoring device processor shall be maintained for
inspection by the employee and the Department pursuant to the requirements of
N.J.A.C. 7:28-8.
(b) Electron microscopes incapable of
operating at 30 kVp or above shall be exempt from the requirements of (a)4
above provided the initial or repeat radiation protection survey does not yield
radiation levels using maximum conditions of operation as measured at five
centimeters from any accessible surface greater than 0.5 millirem per
hour.
(c) The registrant shall
provide a means to secure the electron microscope to prevent unauthorized use
when not in operation. Such means may include, but are not limited to, a locked
console or locked room.
