Canadian Tech Shields Astronauts – and Could Benefit Life on Earth
A $5.5 million contract awarded to Bubble Technology Industries (BTI) of Chalk River, Ontario, marks a significant step forward in protecting astronauts from the dangers of space radiation. The Canadian Space Agency (CSA) is tasking BTI with developing the Canadian Active Neutron Spectrometer (CANS), a compact and autonomous tool designed to measure neutron radiation exposure. This isn’t just about space exploration; the technology developed has potential applications right here on Earth.
The Invisible Threat of Space Radiation
Radiation is a major hurdle for long-duration space missions. Beyond Earth’s protective atmosphere, astronauts face increased exposure to various types of radiation, including neutron radiation. Approximately 30% of radiation within spacecraft is neutron radiation, which is particularly harmful as it can cause biological damage and increase the risk of long-term health problems like bone marrow damage and cancer.
The CANS instrument is designed to specifically target and monitor this neutron radiation, providing crucial data for assessing and mitigating risks as Canada and its international partners plan missions to the Moon and beyond.
Building on Canadian Expertise
This contract isn’t BTI’s first foray into space radiation detection. The company previously developed “bubble monitors” – radiation-detecting tubes – used in the Radi-N2 experiment on the International Space Station (ISS) by astronaut Chris Hadfield. BTI also received a $505,000 Phase A contract from the CSA to develop a prototype for CANS.
Founded in 1988, BTI specializes in hardware and software for defence and aerospace, with a strong focus on radiation detection. Their existing product line includes the FlexSpec neutron radiation sensor kit, adaptable for utilize in vehicles, ships, and even backpacks.
Beyond Space: Terrestrial Applications of Radiation Detection
The benefits of this technology extend far beyond space exploration. Data generated by CANS has potential applications in several fields, including:
- Cancer Therapy: Improving radiation treatment planning and delivery.
- Radiation Protection for Aircrews: Monitoring and minimizing radiation exposure for pilots and flight personnel.
- Nuclear Threat Detection: Enhancing security measures and detecting illicit nuclear materials.
- Nuclear and Particle Physics Research: Advancing scientific understanding of radiation and its effects.
- Public Safety: Improving response to nuclear incidents.
Minister of Industry Mélanie Joly emphasized that the technology will provide “practical data to help protect astronauts from harmful radiation” while also offering benefits to those exposed to radiation in various terrestrial settings.
The Future of Space Radiation Monitoring
CANS represents a significant advancement in radiation monitoring technology. Unlike previous Canadian technologies, CANS is designed to operate continuously and autonomously, reducing the demand for human intervention. This represents crucial for long-duration missions where constant monitoring is essential.
This project reinforces Canada’s role as a key partner in space exploration and demonstrates the country’s commitment to developing cutting-edge space technology.
