Personal Combined Radiation Detectors/Dosimeters PM1703MO-1/MO-2 /MO-1 BT

The PM1703MO-1 and PM1703MO-2 instruments combine features of both Personal Radiation Detector (PRD) and Dosimeter in one housing.

Each instrument is equipped with two detection modules: highly sensitive CsI(Tl) scintillation detector and small-sized GM tube detector. CsI(Tl) scintillation detector allows to search for radioactive and nuclear materials and GM tube detector allows to measure dose rate of gamma radiation in the wide energy range.

PM1703MO-1 BT - This modification is equipped with Bluetooth v 4.0 Low Energy Module (BLE112) and can exchange data with user’s mobile device in real time.

Benefits:

Devices of PM1703 series have equal radiological characteristics with the main competing devices and have a number of user benefits:

  • due to special detection algorithm, devices are able to detect smaller excess in 2-5 times of gamma radiation above the natural background within the time normalized by standards. On the other hand, it enables to alarm in shorter time in comparison with the requirements of the standards
  • due to operating time from one AA battery up to 1000 h., benefit in operating cost of the device over 6-year period is achieved: for РМ1703 series – not more than 50 dollars, for other competing devices – 180-1000 dollars
  • at the same time devices of the PM1703 Series remain one of the smallest PRDs in the world
  • devices of PM1703 series is the best value for reasonable price

The PM1703MO-1 and PM1703MO-2 models offer the highest performance of this type instruments which are currently available on the market. They meet requirements of applicable sections of ITRAP/IAEA, IEC 60846, IEC 62401, ANSI N42.32 and ANSI N42.33 standards.

The PM1703MO family instruments combine functionality of both Personal Radiation Detector and Dosimeter in the one package. The highly sensitive CsI(Tl) based detector ensures prompt gamma radiation detection and source location and together with GM tube detector enables precise dose rate measurement.

Instrument enables activity registration of the 134Cs, 137Cs radionuclides presented in different samples, such as food, drinking water, different liquids, crumbling construction materials, soil, etc. Besides, my means of the instrument the activity of the radionuclides in many wrapped/packed samples can be evaluated, meat, fish, etc. in pieces or carcasses weighting up to 50 kg.


The instrument enables the following modes:

  • registration of the specific (volumetric) activity without preliminary sample preparation (from 100 Bq/kg (Bq/l) to 9999 Bq/kg (Bq/l) at background level no more than 0.15 µSv/h
  • registration of surface activity in soil in situ registration geometry (without taking samples from the natural occurrence places) from 0.5 to 99.9 Bq/cm2.

The compact form factor of instruments allows easy fit on the user’s utility belt. Optional battery charger/cradle with sun protective screen enables effortless placement of the instrument on the vehicle dash board

The range of the possible applications varies from the health physics needs and the personnel acute dose monitoring to the security applications and area monitoring.

The PM1703MO family instruments are available in two versions:

PM1703MO-1

The instrument features expanded dose rate measurement range and large LCD for better result readings. Additionally, the PM1703MO-1 model is equipped with the optional vehicle charger/mounting cradle for easy placement on the vehicle dash board.

PM1703MO-1 BT

This modification is equipped with Bluetooth v 4.0 Low Energy Module (BLE112) and can exchange data with user’s mobile device in real time. Mobile apps (for iOS and Android) can be downloaded from the App StoreSM or from Google PlayTM.

PM1703MO-2

This modification fulfills requirements of the International Atomic Energy Agency (IAEA) and is widely used for radiation security needs at the international events.
