Personal Nuclear radiation alarm dosimeter

1. Overview

LK-3600 personal radiation alarm dosimeter is a kind of small-scale equipment, which is made by new SCM technology, can work in relatively harsh environment, and with strong anti-interference ability. It mainly used to detect χ rays and γ ray, according to LCD screen you can directly read the "dose rate"; "accumulated dose" and "storage accumulated dose". In the range of measurement, the value can be pre-fixed or threshold pre-alarmed, it would sound-light alarm when the value displayed exceed the threshold or blocked, prevent workers from being injured by excessive dose. The instrument is low power consumption, multi-function, small size, convenient taking. It is widely used in NDT, nuclear power station, nuclear submarine, isotope application and hospital cobalt treatment etc.

2. Features

1,High sensitivity, stable and reliable.

2,Super LCD English display functions, state display at a glance.

3,When measuring radiation dose rate, display dose rate, accumulated dose and storage accumulated dose, it has variety of selections on dose rate Alarm threshold. According to the high-low of dose rate and accuracy choice the measure time, general measure time is 02s.

4,General cases, nature dose rate and cumulative dose do not display, don't participate in measurement, this improved equipment’s reliability and precision.

5,Specially designed the nature test function, it can testing equipment work normally or not, convenient to self-check and measuring department examination.

6,With accumulated dose memory function, after power –failure, data can be stored permanently, and don’t lost.

7,Low power consumption, multi-function, small size, convenient taking.

8,Simple operation and easy to use.

3.Main Technical Performances

1,Through G-M counter compensation, improve the low-energy response.

2,Instrument with high sensitive, will respond to the environment nature.

3,For radiation occasions γ, χ rays.

4,Measuring range, dose rate:  0.01usv/h—5msv/h
  accumulated dose: 5-
digit LCD display 000.01—999.99msv

5,Energy response: <±30% (50KeV—1.3MeV).

6,Relative basic error: <±10%(137Cs Source 662 KeV γ Radiation 1msv/h).

7,Alarm response time: ≤3 seconds.

8,Alarm function

Dose rate threshold alarm: alarm threshold value: 0.5,1.0,2.5,10,30,50usv/h.

  9,With accumulated dose memory function, after power-failure, data can be stored permanently, it can undertake 100 million times storage and erased.

    10,Battery voltage indication.

Icon shows the battery voltage in the upper right corner of instrument LCD, battery label full of three grids, the power is about 2.8V-3.2V, battery label full of two grids, the power is about 2.5V-2.8V, battery label full of one grid,the power is about 2.1 V-2.5V, battery label without full of grid , the power is under 2.1V, it is in the state of less power. 
  11,Working environment requirements:

Temperature-10 - +50   Humidity: reach 90% (no condensation)
