Questions and answers

What parameters determine the radiation energy produced by medical machines?

Machines used in medicine produce varying amounts of radiation energy based on what parameters? (paragraph 1)

What should be recorded for a device or material that is not listed on the installation inventory?

If device/material is not listed on the installation inventory, record all pertinent information to report to IRSO. (paragraph 3)

How can information about an x-ray emitter be found when its labels are missing?

X-Ray tubes should be labeled with a radiation sticker, if KvP and mA settings are not labeled on machine, other sources of intel should be used, such as an interview with the operator. (paragraph 2)

What should be considered when determining priority for special surveillance?

Take in to consideration operators/users, adjacent rooms and areas, and if area is accessible by the general public. (paragraph 4)

When may new radiation sources be reported or identified?

New sources may be reported from a shop supervisor or identified during routine or special surveillance.
