1.Summary:
LK-3000 personal alarm dosimeter is a kind of lapel monitoring instruments,mainly used to survey X-ray and Y-ray,it has high sensitivity, the instrument also has response to have environmental background radiation.
The frequency of sounding and flashing shows radiation field intensity, if more than radiation level, the instrument will send out continuous sounding and flashing, when the counting tube of the instrument blocked, the instruments still emits continuous sound-light alarm. This instrument is of low consumption, many functions, small size and portable, it widely used in industrial NDT, nuclear power station, nuclear submarine, isotope application, cobalt therapy in hospital and so on.
2.the main technical characteristics:
detectors: using the G-M J705 β γ type halogen counter tube.
Radiation field and measuring range: applicable X γ radiation field, the biggest allows measuring rate 5R/h.
energy response: 30Kev-60Co,-40%-+80%.
Noise and alarm: every sound dose equivalent to 2μR.every second dose equivalent to 5mR/h.When the radiation field dose rate is more than 10mR/h, instrument will continuous sound-light alarm.
Power supply: two 7# battery,power dissipation < 1mw
Dimension: 88×44×24(mm)
Operation temperature: -10°C--+40°C
