Conversion coefficients from fluence and air kerma to dose equivalent quantities

Journal of Radiological Protection, 1990
Following the publication of the International Commission on Radiation Units and Measurements Report 39 (ICRU, 1985), the British Committee on Radiation Units and Measurements issued a memorandum (BCRU, 1986) recommending the adoption of the quantities ambient dose equivalent H*(d) and directional dose equivalent H'(d) for area monitoring in the UK ...

Characterization of the response of a well chamber to different models of Ir-192 sources for HDR brachytherapy

Brazilian Journal of Radiation Sciences
The determination of the reference air kerma rate (KR) with well chambers calibrated using a different model of source than desired can lead to significant errors, affecting both radiological traceability institutions and healthcare facilities.
