Onsite inspectionactivities were performed November 18-20, 2020, at the EIRMC facilities in Idaho Falls, Idaho.The inspector continued in-office review through April 15, 2021. The scope of the inspectionwas to examine the activities conducted under the license and to confirm compliance with theNRC's rules and regulations and with the conditions of the EIRMC license. The inspection alsoincluded additional review of the licensee's corrective actions to address a previously issuedviolation. Based on the results of the inspection, there were four apparent violations identified.The following includes each violation and the four required components for response.Apparent Violation 030-32290/2020-001-01: Failure to monitor individuals' occupationalexposure to radiation and radioactive materials (10 CFR 20.1502).(1) Reason for the Apparent ViolationUpon inspection, based on dosimeter data and interviews, AUl had inconsistent use of theassigned personnel dosimeters during the conduct of procedures involving licensed andunlicensed sources of radiation. AUl was not wearing current month dosimetry badge at thetime of inspection (wearing June badge in December). AUl is an lnterventional RadiologyPhysician that Is not a licensee direct employee, but rather works under the EIRMC license aspart of an independent radiology provider, Medical Imaging Associates. At the time ofinspection, November 2020, AUl was wearing a June 2020 dosimetry badge. Furthermore,inspection revealed that AU1 has not been wearing the dosimetry badge as prescribed by. Landauer and EIRMC policy and procedure. AUl is currently listed on the NRC license as anauthorized user of Yttrium-90 (Y90). AUl performs licensed and unlicensed procedures in thelnterventional Radiology lab.(2) Corrective Steps That Have Been Taken and the Results AchievedEIRMC has completed the following corrective actions which may be duplicated in the responseon subsequent responses to the additional apparent violations in this letter, as each does applyto the dosimetry badge process, radiation safety program and education In regards to radiationsafety at EIRMC. Revised policy "Guidelines for Radiation Safety, Ref #1425, Ver. 9" (see Appendix 1} wasapproved by Jeffrey Sollis, CEO on December 3, 2020. Revisions include proper wear and2

Document Owner: Kade Price (Dir Dia nostlc Imaging)Manual: Medical Imaging Medical ImagingRef#: 142S Ver: 9Date Approved: 05/17/2021Next Review: 1/23/2024Approved: Kade Price (Dir Diagnostic Imaging)Page: 1 of4Title: Guidelines for Radiation SafetyI.RADIATION SAFETY RULESLead aprons should be worn during all fluoroscopic examinations. Whenever it becomes necessaryfor a technologist to hold a patient during x-ray exposure, lead gloves and lead aprons should beworn. Lead Aprons/Thyroid Shield integrity is done through proper QC procedures performedannually. QC ls performed on all new aprons.During an x-ray exposure the door to the hall must be closed to eliminate the possibility of exposureto any passerby as well as for privacy. The technologist should remain within the shielded area of thecontrol panel while making an exposure.When performing portable x-ray procedures, a lead apron should be worn by the technologist. Thetechnologist must also remove him/herself as far as possible from the source of the radiation. Prior tothe exposure, the technologists will inform those present in the room, and allow time for those notrequired to remain in the room during the exposure to either leave or increase their distance andlocation from the radiation source. Lead aprons should be worn if remaining in the room during theexposureAnyone accompanying a patient to a room where ionizing radiations are used, a lead apron will beworn or the individual will stand behind the shielded area. This applies to any accompanying personsor assisting personnel.Cancer Center - The patient is the only one allowed in the treatment vault during treatment.Nuclear Medicine - Those accompanying the patient will be discouraged from remaining in theNuclear Medicine rooms during image acquisition to decrease potential exposure. Those who wish toremain in the Nuclear Medicine rooms during Imaging acquisition will be instructed on how to reducepotential exposure.Coning to film size or less will be carried out on every exposure; this includes portable procedures.Proper gonadal shielding is required for all patients where it is reasonable to do so.All patients who are not responsible for their actions are not to be left alone in the x-ray rooms orwaiting areas. Should any incident occur either to the patient, personnel or visitor, an occurrencereport should be documented by the individual who discovered the incident. The Radiation SafetyOfficer (RSO) and department director are also to be informed of the incident immediately.Should any malfunction of equipment occur either electrically or mechanically, use of that room isdiscontinued until repaired by maintenance or service vendor. Ali weights and counterbalance cablesare checked periodically by service vendor for wear and replaced as needed. In case of electricalproblem. the machine is turned off.Technologists must report to supervising technologist any notice of wear, malfunction or irregularity inequipment.In case of fire, a carbon dioxide extinguisher is located in several locations for quick access from anyequipment area, and the fire alarm given according to the hospital fire rules.

The age range is from menses to menopause. Ifthe question arises to the possibility of pregnancy, or it has been more than 10 days since thepatient's last period, a radiologist will be consulted prior to the examination being done. The PreExamination Pregnancy Determination form will be sent to HIM and Is part of the permanent medicalrecord.II. DOSIMETRY BADGESAll personnel having direct contact with patients who have been injected with a radioisotope or whoconduct the duties and functions of their job in areas of radiation exposure will be required to wear aradiation dosimetry badge while on duty. This includes technologists, radiologists, physicians,contract workers, and all staff that assist in radiological procedures or procedures where radiationexposure occurs. Dosimetry badges for monitoring of radiation exposures are provided for personnelin medical imaging, interventional radiology, the cancer center, cardiology, biomedical services, theOR, endoscopy and others as requested.Education on proper dosimeter badge wear-and-handling will be given to all participants upon hire.Every effort will be made to determine occupational dose by requesting exposure reports from prior orconcurrent employer.Facility radiation film badges will be monitored monthly by Landauer, Inc. Dosimetry badges will becollected at the end of each month with replacement badges available. It is the responsibility of thestaff member or physician to switch out their film badges at the time of collection. Monthly andquarterly reports will be available to all monitored staff.Whole body dosimeters (that is, when one dosimeter is worn) must be worn on the portion of the bodywhich is likely to receive the highest dose. If a lead apron is worn, the dosimeter should be wornoutside the lead apron at the collar or neck.If two dosimeters are worn at the same time (e.g. one at the collar and one at the chest or waist underthe lead apron), care must be taken to always wear the dosimeters in their correct locations. That is,the "collar" badge must always be wom at the collar and the "waist badge must always be worn atthe waist. Verify the date of use and badge-type designation when inserting into the plastic coloredholders.If a worker wears a lead apron and a thyroid shield, the badge is worn outside the apron and theshield and the dose is an "eye dose". If a wor1 er wears a lead apron, thyroid shield and lead glasses,then the dosimeter is wom under the lead apron or thyroid shield.A second dosimetry badge will be provided to technologists wor1 ing In the interventional suite due topotential risk of receiving higher doses. The second badge is to be worn at the collar, underneath thethyroid shield. The holder is to be clipped at the proper location with printed side out.
