MITECH MT3600 Personal Radiational Alarm Dosimeter



MT3600 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 is mainly used to detect χ ray, γ ray and βray, according to LCD screen you can directly read the "RATE", "DOSE" and "STORE DOSE". In the range of measurement, the value can be pre-fixed or threshold pre-alarmed, it would emit 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.


  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. When measure relatively small doses, please select 10 or 20 seconds.
  4. Specially designed the nature test function, it can test if the equipment works  normally, convenient to self-check and measuring department examination.
  5. With accumulated dose memory function, after power –failure, data can be stored permanently, and don’t lost.
  6. Low power consumption, multi-function, small size, convenient taking.
  7. Simple operation and easy to use.

Main Technical Performances

  • Through G-M counter compensation, improve the low-energy response.
  • Instrument with high sensitivity, will respond to the natural environment.
  • For radiation occasions γ, χ ,βrays.
  • Measuring range, dose rate: 0.000usv/h—5msv/h

accumulated dose: 6-digit LCD display 000.000—999.999msv

  • Energy response: <±30% (50KeV—1.3MeV).
  • Relative basic error: <±10%(137Cs Source 662 KeV γ Radiation 1msv/h).
  • Alarm response time: ≤3 seconds.
  • Alarm function
  • Dose rate threshold alarm: alarm threshold value: 0.5,1.0,2.5,10,30,50usv/h.
  • With accumulated dose memory function, after power-failure, data can be stored permanently, it can undertake 1 million times storage and erased.
  • Battery voltage indication. 
  • Icon shows the battery voltage in the upper right corner of Instrument LCD, when battery shows three full grids, power is about 2.8V-3.2V, when battery shows two grids, the power is about 2.5V-2.8V, when battery shows one grid, the power is about 2.1 V-2.5V, when battery shows without grid , the power is under 2.1V, it is in the state of less power.
  • Working environment requirements:
  • Temperature:-10 - +50℃ Humidity: reach 90% (no condensation)
  • Weight:130g (not including battery )   
  • Size: 150mm x 73mm x 31mm


Report recommended by ICRP60.

Radiation dose limit for the professionals: the effective dose of 5 years 100msv, average annual 20msv, but any year can not exceed 50msv.

Dose limit for residents:1 msv /year (if the average is not more than 1msv in continuous 5 years ,individual years may be slightly higher.)
Radiation dose and dose equivalent relationship can be showed as:


1u sv · h-1≈0.1R· h-1
