The PM1401K is an unique light-weight multipurpose hand held radionuclide identifier designed for easy detection and location of the alpha, beta, gamma and neutron radiation sources, precise measurement of the alpha and beta surface contamination levels and gamma dose rate, and reliable identification of the radioisotopes. For example, the PM1401K is able to distinguish between naturally occurring radiation materials (NORM), medical isotopes, industrial sources of radiation, which are potentially dangerous to the general population, and of the sources of radiation that are inherently dangerous, such as weapons-grade nuclear materials.

The PM1401K performs the following functions:

• Isotope identification both a single radionuclide and their mixtures;
• Detect, search and locate the alpha, beta, gamma and neutron radiation sources including nuclear weapon materials;
• Measurement of the alpha and beta surface contamination levels;
• Accurate measurement of the dose rate;
• User alert of the presence of a radiation source through both audible and vibrating alarms;
• Recording and storing up to 500 event and 100 gamma spectra in its non-volatile memory;
• Transmitting all of the recorded data via IR or radio (Bluetooth) channels to a PC or PDA.

In contrast to the conventional radionuclide identifiers which need a calibration source build in and/or a regular calibration procedure for correct operation, the PM1401K does not require calibration due to the stable parameters of the CsI(Tl) crystal deployed in unique scintillation crystal-photodiode packing technology. The PM1401K can be used for the radioisotope identification of the radiation source using its build-in Bluetooth communication module and Polimaster proprietary identification software for PDA or laptop PC.

Identification software can be utilized in two operation modes: automatic mode for non-trained users and expert mode for advanced users.

The Bluetooth communication between PM1401K and PDA (laptop PC) allows user to be at a safe distance from the possible radiation sources while the PM1401K is operating.

The identifiers's small, hermetic and shockproof case and the fluorescent backlight on the instrument's LCD screen allow for easy operation even in the harshest, most unfavorable environments or weather conditions.

Polimaster's PM1401K hand held radionuclide identification device can also be equipped with various functional accessories, including:

• External Vibration-Alarming Device that allows the instruments user to be notified secretly of potential radiation sources without drawing the attention of other observers;
• Telescopic Extension Tube, which allows the instrument to take measurements in otherwise difficult-to-access areas and ensures a higher degree of radiation protection for the user;
• External Neutron Moderator to increase the neutron sensitivity by a factor 10.
