Fla. Admin. Code Ann. R. 64E-5.502 - General Requirements

(1) Administrative Controls.

(a) Registrant. The registrant shall be responsible for directing the operation of the x-ray systems which are subject to registration as described in Rule 64E-5.511, F.A.C. The registrant or the registrant's agent shall assure that the following requirements are met in the operation of the x-ray system.

1. Any x-ray system which does not meet the provisions of these regulations shall not be operated for diagnostic or therapeutic purposes unless the Department determines that such operation will not endanger the public health, safety and welfare.

2. An x-ray system operator shall receive instruction on and be competent in the safe use of the x-ray system. A medical x-ray system operator shall also be certified or authorized in accordance with Chapter 468, Part IV, F.S.

3. A chart shall be provided in the vicinity of the diagnostic x-ray system's control panel, which specifies techniques and procedures to be used for all examinations which are performed by that system.

4. Except for patients who cannot be moved out of the room, only the staff and ancillary personnel required for the medical procedure or training shall be in the room during the radiographic exposure. Other than the patient being examined:

a. All individuals shall be positioned such that no part of the body will be struck by the useful beam unless protected by 0.5 millimeter lead equivalent.

b. Staff and ancillary personnel shall be protected from the direct scatter radiation by protective aprons or whole body protective barriers of not less than 0.25 millimeter lead equivalent.

c. Other patients who cannot be removed from the room shall be protected from the direct scatter radiation by whole body protective barriers of 0.25 millimeter lead equivalent or shall be so positioned that the nearest portion of the body is at least 2 meters from both the tube head and the nearest edge of the useful beam.

d. When a portion of the body of any staff or ancillary personnel is potentially subjected to stray radiation which could result in that individual receiving one-fourth of the maximum permissible dose as defined in Part III, additional protective devices may be required by the Department.

5. Gonad shields of not less than 0.25 millimeter lead equivalent shall be used for patients who have not passed the reproductive age, during radiographic procedures in which the gonads are in the useful beam, except for cases in which this would interfere with the diagnostic procedure.

6. Individuals shall not be exposed to the useful beam except for healing arts purposes and unless such exposure has been authorized by a licensed practitioner of the healing arts. This provision specifically prohibits the following:

a. Exposure of an individual for training, demonstration or other purposes unless there are also healing arts requirements and a proper prescription has been provided.

b. Exposure of an individual for the purpose of a healing arts self-referral program except when authorized by subparagraph 64E-5.502(1)(a) 1., F.A.C.

c. Advertisement of free x-ray examinations unless the advertisement states that a determination of need will be made prior to the x-ray examination.

7. An x-ray system is exempt from the requirements of subparagraph 64E-5.502(1)(a) 6., F.A.C., only if:

a. The system is a stationary, non-mobile system installed and used only in a jail or penal institution;

b. The system is used only on legal detainees in a jail or penal institution, and never on detainees' family members, children, institution employees, contractors, visitors, the public, or any other persons;

c. The system is manufactured, maintained, and operated solely for security screening purposes in strict compliance with, and fully according to, the most restrictive standards found in ANSI/HPS N43.17-2009, "Radiation Safety for Personnel Security Screening Systems Using X-Ray or Gamma Radiation," which is herein incorporated by reference. This ANSI publication may be examined and inspected at the Florida Department of Health, Bureau of Radiation Control at Building 4042 Bald Cypress Way, Suite 210, Tallahassee, Florida 32399-1741, and at the Florida Department of State, Room 701, The Capitol, Tallahassee, Florida 32399-0250, and is available from the American National Standards Institute, Inc., at http://www.ansi.org. The agency has determined that posting the publication on the internet for purposes of public inspection and examination would constitute a violation of federal copyright law; and,

d. The institution tracks radiation dose for each detainee, as specified by ANSI/HPS N43.17-2009, "Radiation Safety for Personnel Security Screening Systems Using X-Ray or Gamma Radiation," to ensure the detainee does not exceed the recommended dose limit.

8. When a patient or film must be provided with auxiliary support during a radiation exposure:

a. Mechanical holding devices shall be used when the technique permits;

b. Written safety procedures shall be available to indicate the requirements for selecting a holder, list the individual projections where holding devices cannot be used and describe the procedure the holder shall follow;

c. The human holder shall be protected as required by subparagraph (1)(a)4., above; and,

(I) Licensed practitioner as that term is defined in Section 468.301, F.S.; or

(II) Certified radiologist assistant practicing in accordance with the requirements of Chapter 468, Part IV, F.S.; or

(III) Certified general radiographer practicing in accordance with the requirements of Chapter 468, Part IV, F.S.; and

(A) The general radiographer has been trained and authorized in writing by the licensed practitioner in charge to perform the specified imaging; and

(B) The specified imaging does not rely upon the general radiographer to provide any diagnostic interpretation, or to determine suspicious areas for additional imaging, or to otherwise modify the scope of authorization for the imaging; and

(C) The specified imaging is designed to prevent or reduce exposure to patients by facilitating proper location and positioning for the authorized radiographic imaging.

10. Personnel Monitoring. All individuals who are associated with the operation of an x-ray system are subject to the occupational exposure limits and the requirements for the determination of the doses stated in Rules 64E-5.304 and 64E-5.308, F.A.C. In addition, when protective clothing or devices are worn on portions of the body and a personnel monitoring device is required, at least one such device shall be utilized as follows:

a. When a protective apron is worn, the monitoring device shall be worn at the collar outside of the apron.

b. The dose to the whole body shall be recorded in the records required by Rule 64E-5.339, F.A.C. If more than one device is used and a record is made of the data, each dose shall be identified with the area where the device was worn on the body.

(a) Processing Facilities. Each installation using a radiographic x-ray system shall provide suitable equipment for handling and processing radiographic film in accordance with the following provisions:

1. The area in which undeveloped films are handled for processing shall be devoid of light with the exception of light in the wave lengths having no significant effect on the radiographic film.

2. Film pass boxes, if provided, shall be so constructed as to exclude light when film is placed in or removed from the boxes, and shall incorporate adequate shielding to prevent exposure of undeveloped film to stray radiation.

3. Darkrooms used by more than one individual shall be provided a positive method to prevent accidental entry while undeveloped films are being handled or processed.

(II) Signal the passage of a preset time as short as 2 minutes.

(b) Precautionary Practices.

1. Film shall be stored in a cool, dry place and shall be protected from exposure to stray radiation. Film in open packages shall be stored in a light tight container.

2. Film cassettes and intensifying screens shall be inspected periodically and shall be cleaned and replaced as necessary to best assure radiographs of good diagnostic quality.

3. Outdated x-ray film shall not be used for human diagnostic radiographs, unless the film has been stored in accordance with the manufacturer's recommendations and a sample of the film passes a sensitometric test for normal ranges of base fog and speed.

4. Film developing solutions shall be prepared in accordance with the directions given by the manufacturer, and shall be maintained in strength by replenishment or renewal so that full development is accomplished within the time specified by the manufacturer.
