Electrometers used for radiotherapy applications should meet the requirements of 'IPEM recommendations on dosemeter systems for use as transfer instruments between the UK primary dosimetry standards laboratory (NPL) and radiotherapy centres', Institute of Physics and Engineering in Medicine (IPEM) 2000, Phys. Med. Biol., 45 pp 2445-57
An electrometer can be submitted on its own for calibration at any time or with an associated secondary standard ionisation chamber during annual calibration periods for therapy level, brachytherapy or protection level instruments.
Turnaround time is approximately two weeks if calibrated alone. Uncertainty of calibration is estimated to be ± 0.2 % (k=2).
