Personal radiation monitor for electric fields with on site interchangeable sensor modules

Nardalert S3 is worn on the body and gives visible, audible and vibratory warning when the electric field power density approaches or exceeds the permitted limit. The warning thresholds are user settable. Different sensor modules that can be exchanged on site are available for various human safety standards.

Sensor modules are available for the following human safety standards:

ARPANSA RP3, occupational
Canada Safety Code 6 (2015)
EMF Directive 2013/35/EU
FCC 1997 occupational / controlled
ICNIRP 1998 occupational
IEEE C95.1-2005/ANSI C95.1-2005 controlled
Japan RCR-38 controlled
