What is a Level Ib audit?
The onsite Level Ib audit offers a more accurate measurement of the linac output than the Level I audit and determines the absorbed dose to water per monitor unit for megavoltage photon and electron beams under reference conditions. We visit your facility and perform onsite measurements in your facility's own water tank. All other dosimetry equipment is brought in by us, ensuring an independent audit.

Audit coverage
The Level Ib audit is not part of the scheduled program and is performed at the request of your facility. It's typically conducted for new facilities or linacs, or as a part of the follow up process where other audits fall outside the passing levels.
