Following approval by the RSC, the Radiation Equipment Supervisor becomes responsible for all radiation related activities that are performed or required to be performed in accordance with the conditions of approval. Responsibilities include, but are not limited to, relevant equipment purchase, safety surveys, and protocol development and implementation.
The RES is responsible for ensuring that individuals in their laboratory who work with ionizing radiation or who are exposed to ionizing as a result of activities conducted under their supervision, are properly trained and aware of the related hazards. The RES must also ensure that only approved radiation equipment procedures are performed in the laboratory and that the RSO is notified of any changes in use areas, equipment, individuals or procedures. A summary of the responsibilities of a Radiation Supervisor are provided in Section 1.
Any additions or modifications to approved procedures or radiation-producing equipment use that could potentially increase or modify the radiation hazard previously evaluated or introduce a new hazard, must be approved by the RSC prior to commencement. In general, a RES must:.
Syracuse University requires that anyone who wishes to work with radiation-producing equipment have a thorough understanding of regulations and hazards associated with the use of ionizing radiation.
This is accomplished through a two stage radiation worker training program. Stage One of this program must be completed prior to commencing work with ionizing radiation. Stage Two must be completed in the laboratory under the direct supervision of the RES. The following lists the steps for completing both stages of the required radiation equipment operator training program:.
The registration is renewed biennially and as changes occur. This log must contain the name of the operator, the date, the duration of use time on and off , and the purpose of the operation. These SOPs must minimally include procedures for all routine operations, sample changes, beam alignments, and emergency shut down. All registered ionizing radiation-producing equipment is inspected biennially by the NYSDOH for compliance with applicable portions of State regulations and issued guidelines.
The Radiation Safety staff will perform inspections on registered equipment at six month intervals or as necessary to ensure the safety of operating personnel electron microscopes are inspected annually.

No person shall operate or permit the operation of a radiation installation nor shall the person operate, transfer, receive, possess or use or permit the operation, transfer, receipt, possession or use of any radiation source unless that person: a achieves occupational doses and doses to members of the public as low as is reasonably achievable ALARA.
The committee, or a subcommittee, shall also oversee the administration of a quality assurance program, as required by subdivision d of this section; e provides a quality assurance program for diagnostic and therapeutic uses of radiation producing equipment and radioactive materials pursuant to section Medical physicists, radiologic technologists, in-house engineering, and manufacturer service representatives are responsible for various aspects of equipment evaluation or performance.
The QA responsibilities for each party shall be defined as a manual item. Records shall be maintained and available for review for QC test equipment that requires calibration. QC records may be maintained in either a hardcopy or softcopy format, but must be available for review during inspections and whenever else they are needed. The written policy and procedures must be available on the holding of patients; pregnant patients and operators; and personnel monitoring.
Each facility shall make or have made quality control tests to monitor equipment performance and maintain records of data collected. The tests performed will vary from manufacturer to manufacturer but must include those quality control checks specified by the manufacturer and be modeled after the program below. If, at the time of inspection, significant equipment malfunctions are found, the facility may be required to perform more frequent testing to ensure good diagnostic image quality.
Facilities with equipment not under warranty or service contract must follow the testing frequency stated in this guide. Facilities must perform all the QC tests which their manufacturer supplied phantom will allow.
Appropriate quality control testing must be conducted whenever major maintenance X-ray tube replacement or a change in equipment operation software change occurs. Equipment functioning: Each day during equipment warm-up, and before scanning the first patient, the operator must check for any malfunction. The operator must also evaluate the mechanical and electrical safety of the CT system. Malfunctions and unsafe conditions shall be corrected promptly. CT Number Accuracy of Water, Image Noise, Image Uniformity, and Artifact evaluation shall be performed daily using a common technique setting with a head sized phantom.
The average CT number and standard deviation of noise must be performed using a region of interest that is standardized for the QA tests.
Image uniformity and artifact evaluation must be done using an appropriate and consistent window level and width. Performed at each available slice thickness, using an appropriate phantom for both the axial and helical modes of operation. Evaluate the accuracy of slice localization lights, the accuracy of slice positioning and the accuracy of table motion with incrementation. CT numbers must be evaluated using a phantom containing a variety of materials to evaluate a wide range of CT numbers. The measured values must remain within manufacturer's specifications.
Hard copy devices and dry image processors must be monitored for consistency in accordance with the manufacturers published recommendations. Many of these devices utilize a SMPTE test pattern, which can be readily used and printed for review.
This test must be performed at each available slice thickness. This test can readily be performed using packaged film, which is placed around the surface of the phantom.
Alternative methods of evaluation can also be used. Multiple slice units need to be evaluated for over-beaming and adjusted to manufacturer's specifications.
