4 About this device
14 RadMan 2LT/2XT
4.4 Standard conformity
The permissible limit values specified in the standards are frequency-depen-
dent. Weighting filters in the sensors of the RadMan 2 simulate the frequency
response of the standard. They ensure that the alarm thresholds are correct
over the entire frequency range. Settings are not necessary. Underlying
safety standards:
• ICNIRP 1998 / Occupational (corresponds to Directive 2013/35/EU)
• FCC 96-326 / Occupational
• Canada Safety Code 6 (2015) / Controlled
• ICNIRP 1998 / General Public, E-Field (RadMan 2LT only)
4.5 Sensor technology
At close range to a radiation source, the otherwise fixed relationship between
an electric field and magnetic field no longer applies. Both field types must
therefore be checked. RadMan 2 is equipped with E-field and H-field sensors
and thus warns reliably, independent of the distance to the radiation source.
Automatic sensor test
The newly developed sensor test tests the proper function of the individual
sensors each time the device is switched on. The device no longer needs to
be tested with a test generator prior to beginning work.
4.6 Body effects
The radiation monitors are mainly worn on the body. For simple fastening to
a climbing harness or belt, RadMan 2 includes a suitable holder with inte-
grated RF absorber. The RF absorber reduces the signal reflections caused
by the body that would affect the results output by the monitor. If necessary,
the RadMan 2 can be removed from the holder with one hand to determine
the field exposure off the body with isotropic directional response. An elastic
safety lanyard between the device and holder protects the device from falling
down.
