UST company has a long-term experience with the development of dosimeters and spectrometers primarily intended for scientific purposes. Examples of its products include open-source dosimeters for primary and secondary cosmic radiation - the SPACEDOS, AIRDOS and GEODOS series, that are indeed very unique in their properties.

UST’s dosimeters are not used only for terrestrial purposes. They have already successfully participated in several space missions. SPACEDOS02 measures, for a period of a regular crew change lasting several months, aboard International Space Station (ISS). SPACEDOS01 dosimeter has been modified for mounting inside cubesats and was sent to Earth’s orbit as a part of SOCRAT-R satellite.

SPACEDOS and AIRDOS dosimeters are high-quality, durable and simply modifiable devices that can be easily customized, including specific mounting requirements, the choice of power supply, volume of the sensing element, the range of measured energies and more.

Concerning the development of the detectors, we have established a long term cooperation with the Nuclear Physics Institute of the CAS (Department of Radiation Dosimetry), in the framework of project CRREAT.

Overview of UST dosimetres.

List of UST dosimeters

Type Sensing element Typical use case Notes
LABDOS01 Si PIN diode universal experimental Powered and data output to USB, optional SDcard storage.
SPACEDOS01 Si PIN diode Cubesat, satellites Designed for SOCRAT-R mission. External power supply needed.
SPACEDOS02 Si PIN diode Manned space missions ISS Space Heritage. Self powered from batteries.
SPACEDOS03 Si PIN diode Manned space missions Optimized for testing of cosmic ray shielding. Self powered from batteries.
AIRDOS01 Si PIN diode Aircraft The first version of a semiconductor dosimeter for monitoring the dose obtained during civil flights. Equivalent to Liulin aircraft dosimeters. Self powered from batteries.
AIRDOS02 Si PIN diode Aircraft An improved version of AIRDOS01 dosimeter. Self powered from batteries.
AIRDOS03 Si PIN diode UAV Semiconductor-based detector designed for UAVs. Optimized to use with TF-ATMON system.
AIRDOSF01 Si PIN diode Aircraft Si diode rotated 90 degrees compared to AIRDOS01 dosimeter. Self powered from batteries.
AIRDOSC01 CRY19, SiPM Aircraft Scintillation-based detector designed for aircraft and UAVs. Self powered from batteries.
GEODOS01 Nai(Tl), SiPM Terrestrial use (static) Scintilation dosimeter and spectrometer designed for outdoor, static and long-term installation in areas with difficult access. The dosimeter is equipted with an inbuild logger and the LoRa IoT transmitter. Self powered by photovoltaic cells.
GEODOS02 Nai(Tl), SiPM Terrestrial use (mobile) Scintilation dosimeter and spectrometer designed for outdoor, short-term measurement in remote areas. The instrument needs external data logger, time source and power supply.


LABDOS01 is a lightweight portable dosimeter intended as experimental device for laboratory measurements. The dosimeter is connected via USB bus, through which it is powered and read-out. This minimizes the demand of skills required to operate the dosimeter.

This device should be used for experimental verification and planing before using our more sophisticated and application-specific devices like SPACEDOS, AIRDOS or GEODOS.
