8) entrance IR window for PC connection via reading device to preset systemic alarm

9) contacts of accumulator battery placed on the lower side of the casing.
1.4.2 The dosimeter provides operational individual monitoring of personnel and sound
and light alarming in case of the rate of
Operational individual monitoring of dose consumption for personnel of nuclear industry
enterprises and others concerned with operation of power reactor facilities, handling, processing,
and transportation of production containing radioactive materials. The dosimeters may be
applied in medicine for radiotherapy and diagnostics as well as used by environmental, sanitary,
and customs service.
ATTENTION! THE DEVICE SIDE WITHOUT CLIP HAS TO BE PLACED TO THE
BODY DIRECTION.
The dosimeter presumes the setting of two levels of
accidental presets, which exceeding is dosimeter user distinguished according to the character of
the sound signal. If the preventive
sound tone signals would occur, whereas the accidental
threshold are exceeded, tone signals have 250 ms duration each.
Alarm signal occurred in case of the exceeding any threshold would be automatically
terminated, if the new rate of
alarm preset. This function provides user to automatically stop the alarm signal, if he/she has left
the radiation field of dangerous (threshold) rate of
