Radiansa: radiation measurement and shielding


radiacion de antenas

Hand-held radioisotope identifiers:
portable spectrometers for identification of radioactive material

Devices able to identify radioactive isotopes by analyzing the characteristic gamma emission spectra. The devices are often multipurpose/multitask instruments able to detect different forms of radiation and perform a variety of functions; used to search, detect and identify radioactive materials.


PM1401K-3 Multipurpose radiation detector and radionuclide identifier

PM1401K3 detector de radiación e indentificador de radionuclidos

PM1401K-3 is the smallest and the most lightweight instrument in the world able to operate simultaneously as a search instrument, asurvey meter, an alarm device, a surface contamination monitor, and a radionuclide identifier.

All radiation sensors are internally incorporated in the instrument's IP65 body. Data such as gamma spectra, doserate, etc are shown on a bright and easy-to-read colour LCD; a belt clip and automatic operation mode allow for hand-free operation, while the user goes about their normal tasks.

The instrument's non-volatile memory can store 10000 events and 1000 gamma spectra; data is transmitted externally via a USB port. The instrument incorporates a GPS module.

Optional extras include a telescopic extension tube,m a tripod, and Marinelli beakers for measuring radioactivity in water, food and soild samples.

The PM1401K-3 multipurpose radiation monitor is available in 4 versiones:

  • РМ1401К-3: equipped with built-in alpha, beta, gamma and neutron detectors
  • РМ1401К-3М: modification equipped with built-in alpha, beta and gamma detectors, without neutron detection capabilities
  • PM1401K-3E: gamma-neutron modification without function of 137Cs activity measurement and radionuclide indentification
  • РМ1401К-3P: modification equipped with built-in alpha, beta, gamma and neutron based on three scintillation detector units

El PM1401K-3 is able to fulfil a number of diverse functions:

· Radionuclide identification (PM1401K-3/3M/3P): The CsI scintillation detector analyses the characteristic gamma radiation spectrum of the radionuclide to identify the radioactive material present.

· Search for radioactive sources (PM1401K-3/3M/3E/3P): The high sensitivity of the solid-state CsI sensor aloows search and localization of radiation sources with high efficiency, including hidden sources.

· Surface contamination detection and measurement (PM1401K-3/3M/3E/3P): A Geiger-Müller sensor detects radioactiva contamination of surfaces alpha and beta emitting radionuclides.

· Measurement of ambient gamma doserate (PM1401K-3/3M/3E/3P): Dose rate measurement is performed by the internal Geiger-Müller sensor

· Detection of neutron emitters (PM1401K-3/3E/3P): A nuetron sensor (He3 - no export restrictions) is used to amplify the instrument's response to special nuclear materials (uranium and plutonuim isotopes)

· Measurement of Cs137 specific activity (PM1401K-3/3M/3P): Specific activity (Bq/kg) of the radionuclide Cs-137 can be measured in food, water, and environmental samples.
