Radi-N2 Bubble Detector experiments on the ISS begin

On Monday, December 3rd, 2018, Canadian astronaut David Saint-Jacques boarded the International Space Station following a successful launch on the Soyuz spacecraft earlier that day.

As part of the Radi-N2 experiment, BTI‘s bubble detectors were deployed on the Soyuz and David will use them to start conducting measurements in January. To commemorate the launch, David was given specially-made BTI stickers and patches, which were also brought on to the ISS.

To learn more about BTI’s bubble detectors, please view this page on our website. For more information on the launch, click here.

BTI Bubble Detectors in Space

On December 3rd, 2018, 6 years after Chris Hadfield’s Radi-N2 mission, Canadian astronaut David Saint-Jacques will be launching to the International Space Station (ISS) to perform radiation measurements during his six-month mission. These measurements will be conducted as part of the Radi-N2 experiment, an experiment that measures astronauts’ exposure to potentially dangerous neutron radiation using bubble detectors – innovative Canadian technology provided by Bubble Technology Industries (BTI).

Through a partnership between BTI, the Canadian Space Agency (CSA) and Let’s Talk Science, a project called Radi-N2 & You will be conducted as part of the Radi-N2 experiment, to foster youth engagement around the topic of radiation exposure. While David Saint-Jacques measures radiation levels with our bubble detectors in space, the Radi-N2 & You project will allow children across Canada to do the same on Earth.

Students and educators will be able to:

  • Measure neutron radiation levels on Earth using bubble detectors made by Bubble Technology Industries;
  • Collect and analyze data and compare their results with information from other participating classrooms in Canada as well as from the ISS;
  • Learn about neutron radiation and its effects on human health;
  • Develop critical thinking and data analysis skills.

To learn from about radiation and the Radi-N2 & You project from David Saint-Jacques, please visit this CSA webpage.

Radi-N2 Bubble Detectors used in ongoing space research aboard the ISS

The Radi-N2 experiment aims to characterize neutron radiation in various locations of the International Space Station (ISS). As part of this experiment, bubble detectors produced by Bubble Technology Industries were deployed in the JPM1D5 area of the ISS. The dose information gathered from these detectors will be used to assess the neutron radiation exposure of astronauts onboard the ISS. For more information, please see NASA’s ISS On-Orbit Status Blog for September 6th, 2018.


From September 23-27 2018, Bubble Technology Industries will be showcasing its latest products at the CVSA Annual Conference and Exhibition in Kansas City, Missouri. Come find us at booth no. 11 to learn about how our state-of-the-art radiation detection products can be used in commercial vehicle safety applications.
