Dr. Martin Smith of Bubble Technology Industries Receives Prestigious International Award

October 13, 2021 (Chalk River, Ontario) – Dr. Martin Smith of Bubble Technology Industries (BTI) has been awarded the prestigious 1906 Award from the International Electrotechnical Commission (IEC). This international award is in recognition of Dr. Smith’s leadership in the development of a new IEC performance standard on Radiation Protection Instrumentation for Vehicle-Mounted Mobile Systems for the Detection of Illicit Trafficking of Radioactive Materials, as well as for his other technical contributions on radiation protection instrumentation. Dr. Smith was nominated and selected for the award by a panel of international scientists.

Dr. Smith is the Manager of Research and Development at BTI, where he leads a multidisciplinary team focused on developing innovative technologies for detecting radiation and explosives in defence, homeland security, and space missions. Located in Chalk River, BTI has a thirty-year history of cutting-edge technology development. The company’s equipment has flown on over two dozen space missions and has been used to screen for nuclear threats at high-profile events, including US Presidential inaugurations, the Olympics, the Super Bowl, and the World Series of Baseball.

Dr. Smith joined BTI in 2005 and has served as a technical expert in nuclear instrumentation with the IEC since 2009, becoming the Canadian Chair of the Subcommittee on Radiation Protection Instrumentation in 2012.  In this role, he leads the Canadian delegation in providing inputs to international performance standards for radiation detection systems. Dr. Smith completed his PhD in Experimental Nuclear Physics at the University of Liverpool in the United Kingdom and moved to North America in 1999 to continue his career in research. He currently resides in Deep River with his family and is active in the community’s minor soccer and minor hockey programs.

Dr. Harry Ing awarded the Meritorious Service Cross

In recognition of founding BTI and advancing the field of nuclear radiation detection, Her Excellency the Right Honourable Julie Payette, Governor General of Canada, announced that Harry Ing will be awarded the prestigious Meritorious Service Cross. A presentation ceremony hosted by the Governor General will be held at a later date.

The Meritorious Service Cross is one of the highest honours that can be bestowed upon a civilian in Canada and is conferred as a testament to an individual’s outstanding achievement and service to the nation. This decoration was created by Queen Elizabeth II and is awarded by the Governor General to recognize Canadians for exceptional deeds that bring great honour to our country. For more details, please visit the Pembroke Observer website news for July 2nd 2020.



The Canadian Space Agency awarded 7 contracts worth a total of $4.36 million to 5 companies and one university to advance concepts for nano- and micro-rovers, as well as autonomous science instruments. These advancements will serve as the first steps towards landing and conducting Canadian science on the surface of the Moon. Bubble Technology Industries Inc. will develop a spectrometer that will autonomously search for hydrogen to indicate the presence of water and ice near the Moon’s surface.

BTI Hosted CSA and Russian Research Partners To Mark 10 Years of Space Operations on the ISS

On February 24, 2020, Bubble Technology Industries (BTI) hosted partners from the Canadian Space Agency (CSA) and the Russian Institute of Biomedical Problems (IBMP) to mark ten years of successful operation of BTI’s original bubble detector “space mini-reader” on the International Space Station (ISS).

Since 2006, BTI has deployed its unique bubble detectors on the Space Station to measure neutron radiation and help assess the radiation risk to astronauts. These measurements have been conducted by numerous astronauts, including Canadians Robert Thirsk, Chris Hadfield, and most recently David Saint-Jacques. The bubble detectors are analyzed on-board the Space Station using BTI’s unique mini-reader to determine the radiation level at different locations in the Space Station.

The original mini-reader was jointly developed through a Canadian-Russian research collaboration and was designed and built by BTI. It was used on the Space Station from 2006 to 2016 and was recently on exhibit at the Museum of Cosmonautics in Moscow. In the meeting, the Russian research partners returned the original mini-reader to BTI, where it will be used to support studies on the effects of long-term space deployment on the instrument. At the same time, the CSA handed over the latest set of BTI’s bubble detectors to the Russian partners for transport back to Russia and ultimately to the Space Station. For more details, please visit the myFM website news for February 28th, 2020.


Join BTI at the National Homeland Security Conference in Phoenix, Arizona, from June 17 – 20, 2019, hosted at the Phoenix Convention Centre. BTI has over 30 years offering specialized radiation detectors to customers worldwide. The exhibit will feature the latest developments in advanced FlexSpec radiation detection systems for homeland security applications. Come visit us at booth #430 to participate in hands-on demonstrations and discuss operational best practices with members of our knowledgeable and dynamic team! For further information, contact .

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.
