English Abstract A radiation monitoring network with automatic warning
capabilities (LMR) has been established in the Netherlands. For the
detection of gamma radiation exposureratemeters manufactured by Bitt
Technologies are used. The exposureratemeters consist of a proportional
counter tube (type RS02) and a readout unit (type RM10E). The calibration
factor (Nk) and the energy response of six counter tubes was determined by
the National Institute of Public Health and Environmental Protection. The
calibration factors, expressed as the ratio air kerma to reading, were
converted to ambient dose equivalent calibration factors using appropriate
conversion factors taken from Grosswend et. al., 1988. An average ambient
dose equivalent calibration factor of 10.8 mSv.rontgen was
calculated.
