Section R313-35-120 - X-Ray Systems Less than 1 MeV used for Non-Destructive Testing
Universal Citation: UT Admin Code R 313-35-120
Current through Bulletin 2024-06, March 15, 2024
(1) Cabinet x-ray systems.
Cabinet x-ray systems shall meet the requirements of Section R313-35-80.
(2) Fixed Gauges.
(a) Warning Devices. A light, which is
clearly visible from any accessible area around the x-ray system, shall
indicate when the x-ray system is operating.
(b) Personnel Monitoring. Notwithstanding
Subsection R313-15-502(1)(a),
individuals conducting x-ray system maintenance requiring the x-ray beam to be
on shall be provided with and required to wear personnel monitoring
devices.
(3) Industrial and Other X-ray Systems.
(a) Equipment.
(i) The registrant shall perform visual and
operability checks of indication lights and warning lights before use on each
day the equipment is to be used to ensure that the equipment is in good working
condition. If equipment problems are found, the equipment shall be removed from
service until repaired.
(ii)
Inspection and routine maintenance of x-ray systems, interlocks, indication
lights, exposure switches, and cables shall be made at intervals not to exceed
six months or before the first use thereafter to ensure the proper functioning
of components important to safety. If equipment problems are found, the
equipment shall be removed from service until repaired.
(iii) Records demonstrating compliance with
Subsection R313-35-120(3)(a)(i)
shall be made if problems with the equipment are found. These records shall be
maintained for a period of three years.
(iv) Records demonstrating compliance with
Subsection R313-35-120(3)(a)(ii)
shall be made. These records shall be maintained for a period of three
years.
(b) Controls.
X-ray systems that produce a high radiation area shall be controlled to meet
the requirements of Section
R313-15-601.
(c) Personnel Monitoring Requirements.
(i) Registrants shall not permit individuals
to conduct x-ray operations unless each of the following conditions are met.
(A) Individuals shall wear a
thermoluminescent dosimeter or film badge.
(I) Each film badge or thermoluminescent
dosimeter shall be assigned to and worn by only one individual.
(II) Film badges shall be replaced at periods
not to exceed one month and thermoluminescent dosimeters shall be replaced at
periods not to exceed three months.
(B) Individuals shall wear a direct reading
dosimeter if conducting non-destructive testing at a temporary job site or in a
room or building not meeting the requirements of Section
R313-15-301.
(I) Pocket dosimeters shall have a range from
zero to two millisieverts, 200 millirem, and shall be recharged at the
beginning of each shift.
(II)
Direct reading dosimeters shall be read and the exposures recorded at the
beginning and end of each shift. Records shall be maintained for three years
after the record is made.
(III)
Direct reading dosimeters shall be checked at intervals not to exceed 12 months
for correct response to radiation and the results shall be recorded. Records
shall be maintained for a period three years from the date the record is made.
Acceptable dosimeters shall read within plus or minus 20% of the true radiation
exposure.
(IV) If an individual's
ion-chamber pocket dosimeter is found to be off scale or if the individual's
electronic personnel dosimeter reads greater than two millisieverts, 200
millirems, and the possibility of radiation exposure cannot be ruled out as the
cause, the individual's film badge or thermoluminescent dosimeter shall be sent
for processing and evaluation within 24 hours. For personnel dosimeters that do
not require processing, evaluation of the dosimeter shall be started within 24
hours. In addition, the individual shall not resume work with sources of
radiation until a determination of the individual's radiation dose has been
made.
(d) Controls. In addition to the requirements
of Section R313-15-601, barriers, temporary
or otherwise, and pathways leading to high radiation areas shall be identified
in accordance with Section
R313-15-902.
(e) Surveillance. During non-destructive
testing applications conducted at a temporary job site or in a room or building
not meeting the requirements of Section
R313-15-301, the operator shall
maintain continuous direct visual surveillance of the operation to protect
against unauthorized entry into a high radiation area.
