Universal Scientific Technologies (UST) boasts long-term experience of innovation and developing state-of-the-art dosimeters and spectrometers. Our SPACEDOS, AIRDOS, and GEODOS series stand at the forefront of dosimetry technology, catering to an array of scientific applications from terrestrial to cosmic explorations.

Unparalleled Performance

Our dosimeters have ventured beyond terrestrial bounds, marking their presence in space missions and aboard the International Space Station (ISS). The SPACEDOS01, engineered for CubeSat deployments, was sent to Earth’s orbit as a part of the SOCRAT-R satellite. The SPACEDOS02 which logs radiation during ISS crew changes, exemplifies our commitment to supporting cosmic radiation research.

Designed for Customization and Ease of Use

UST’s dosimeters are exceptional for their extremely low power consumption, adaptability, and ease of customization. Whether it’s mounting specifications, power supply options, or measurement range adjustments, our devices are tailored to fit your project’s unique requirements.

Collaborative Excellence

Our enduring partnership with the Nuclear Physics Institute of the CAS (Department of Radiation Dosimetry), under the CRREAT project, underscores our dedication to advancing radiation detection technology through collaborative innovation.
