Tests on the dosimeter comply with the IEC Standard IEC 61525 (1998), and 61526 (1998)
、
and JIS
Standard JIS Z 4312 (2003). Indications on the dosimeter may be interfered by certain factors such
as mobile phones, vibrations, and impacts.
If a hard impact operating on the dosimeter, it may have a crack to the dosimeter. In this case,
it may deteriorate the capabilities in a waterproof and a resistance of radio wave.
