Section 180-8-003 - DEVICE SAFETY REQUIREMENTS

Universal Citation: 180 NE Admin Rules and Regs ch 8 ยง 003

Current through September 17, 2024

Radiation generating devices must meet the requirements of this section.

003.01 WARNING DEVICES. Warning devices must be labeled so their purpose is easily identified. On equipment installed after June 27, 1983, warning devices must have fail-safe characteristics.

003.01(A) WARNING LIGHT LOCATION. An easily visible warning light labeled with the words "X-RAY ON", or words having a similar intent, must be located near any switch that energizes an x-ray tube and must be illuminated only when the tube is energized.

003.02 PORTS. Unused ports on radiation source housings must be secured in the closed position in a way that will prevent unintended opening.

003.03 LABELING. All radiation generating devices must be labeled with a readily visible sign or signs bearing the radiation symbol and the words:

(A) "CAUTION RADIATION - THIS EQUIPMENT PRODUCES RADIATION WHEN ENERGIZED". or words having a similar intent, near any switch that energizes an x-ray tube.

(B) For radiation generating devices with designed openings, for object entries, the following must be posted at or near each opening: "CAUTION " " X-RAY HAZARD: DO NOT INSERT ANY PART OF THE BODY WHEN SYSTEM IS ENERGIZED", or words having similar intent.

(C) "CAUTION - HIGH INTENSITY X-RAY BEAM". or words having a similar intent, if applicable, on the x-ray source housing.

003.04 RADIATION SOURCE HOUSING. Each radiation source housing must be subject to the following requirements:

(A) Each x-ray tube housing must be equipped with an interlock that shuts off the tube if it is removed from the radiation source housing or if the housing is disassembled.

(B) Each port cover or each x-ray tube housing must be constructed so that, with all shutters closed, the radiation measured at a distance of 5 centimeters (cm) from its surface is not capable of producing a dose in excess of 0.025 milliSievert ( 2.5 millirem) in one hour. This limit must be met at any specified tube rating.

003.05 GENERATOR CABINET. Each x-ray generator must be supplied with a protective cabinet which limits leakage radiation measured at a distance of 5 cm from its surface so it is not capable of producing a dose in excess of 2.5 microSievert ( 0.25 millirem) in one hour.
