ATTENTION X-ray Equipment
Users!
Requirements to comply with New York City/Bureau of Radiation Health
(NYC/BRH) Regulations
There are a number of items that operators/owners of medical x-ray
equipment must do in order to comply with NYC/BRH regulations and the CPMC
Joint Radiation Safety Committee (JRSC) provisions. Some of these items
are enumerated below for your edification.
I. New Equipment Acquisitions
-
Contact Radiology Physics (Tel: 212-305-5005) to calculate the radiation
shielding requirements for the x-ray equipment;
-
Install the necessary radiation protection barriers (lead lining to
walls and control booths);
-
Notify the JRSC and Radiology Physics of the impending
new equipment acquisitions;
-
Have Radiology Physics perform a Physics Acceptance Testing of
the X-ray equipment in order to ensure regulatory compliance,
radiation safety and image quality;
-
Have Bio-medcial Engineering perform electrical
grounding checks of the equipment
-
Have Radiology Physics check the radiation shielding for voids,
perform and document a Radiation Protection Survey of the
facility;
-
Make certain that the equipment is covered by the current NYC/BRH
permit for the Medical Center or file for an appropriate NYC/BRH
X-ray equipment permit. Contact the Radiation Safety Office
(RSO) for more information;
-
Make certain that the staff has Radiation Badge Monitors and
receive a lecture from the RSO;
-
Make certain that staff is qualified to operate the X-ray
equipment (physician or registered X-ray technologist) and has
been trained in the proper usage of the equipment;
-
Make certain that FDA compliance forms have been filed by
equipment rendor and copies given to operator/owner of the X-ray
equipment;
-
Assign a staff member to be liaison and attend JRSC
subcommittee meetings (about two per year). Contact Radiology Physics
at 212-305-5005 (or ext. 5-5005).
II. Radiology Physics Services
Radiology Physics must be scheduled to perform the following services in
order to be in compliant with NYC/BRH and JRSC.
-
Complete X-ray equipment QC testing every six months, i.e., twice a
year;
-
Quarterly (every three months) X-ray tube collimator tests;
-
Annual radiation patient dose and scatter radiation assessments;
-
Physics records permanently maintained in Radiology Physics Office;
-
Assistance during NYC/BRH, NYS/ERP and JCAHO inspections;
-
Meetings and required at least annual lectures on Radiation Safety
classes.

INTRODUCTION
It became apparent from several recent discussions with x-ray
supervisors that there is some uncertainty about the QC tests and the
frequency which they must be performed under NYC/BRH regulations. Hence,
as a review, I have listed below those QC tests which are the
responsibility of the x-ray supervisors.
I. DAILY REQUIRED RT QC TESTS
1. Film Processor Sensitometry
A) Speed Index
B) Contrast Index
C) Base Plus Fog Level
D) Developer Temperature
2. Warm-up of X-ray Tubes
3. Visual Checks of X-ray Rooms
4. Maintain a Patient Log Book Containing:
A) Name of Patient;
B) Date of Exam;
C) Type of Examination;
D) # of Views.
5. Records of Any Patient Holding During X-ray Examination
A) Name
B) Date
C) # of views
D) Reason for holding patient
E) Lead apron et cetera that were given to person holding
F) Risks were explained
G) Measured scatter radiation to individual holding patient
obtained from radiation monitor
II. WEEKLY REQUIRED RT QC TESTS
1. CT Scanner Image Quality Checks with A Water Bath
A) Mean CT Number
B) Standard Deviation
III. MONTHLY REQUIRED RT QC TESTS
1. Repeat Rates
2. Multi-format camera evaluations on CT and MRI units
3. Distribution and collection of monthly radiation film badges for
area personnel.
4. Film processor PM to be performed by processor service and
documented.
5. A calibration check of film densitometer used for sensitometry must
be performed and documented.
6. Continuing education lectures for the RT's on Radiation Safety and
Quality Control procedures must be conducted and documented with
names and dates.
IV. QUARTERLY REQUIRED RT QC TESTS
1. Records of film-screen cassette inspection and cleaning (Note
Mammography must clean and inspect cassettes on a weekly basis).
2. Repeat Rate Statistics
V. SEMI-ANNUAL REQUIRED RT QC TESTS
1. Lead aprons, gloves, thyroid shields and drapes must be inspected
for tears and the results documented.
2. Darkroom fog evaluations.
3. Viewbox evaluations.
VI. ANNUALLY REQUIRED RT QC TESTS
1. Reject analysis (Actually, this evaluation should be done more
frequently. Mammography must do this test quarterly.)
2. Technique chart update.
3. Film-screen contact and evaluation of cassettes more than four years
old.
4. PM to be performed on all x-ray equipment and documented.
5. Policy and procedures related to radiation safety must be reviewed,
modified if necessary and dated/signed.
6. Radiation Safety QA/QC Subcommittee must meet and minutes must
document the meeting.
7. License renewals and copies to Radiology Administration.
