LONGUEUIL, QUEBEC -- (Marketwire) -- 03/11/13 -- Did you know that radiation levels aboard the International Space Station (ISS) are hundreds of times higher than the levels here on Earth? To understand this issue better, Canadian Astronaut Chris Hadfield is analyzing radiation levels on the ISS through a Canadian experiment called Radi-N2. On March 11, he will speak on this subject as well as other aspects of his life and work on board the ISS when he connects via video with close to 1000 grade 9 to 12 students from Bert Church High School in Airdrie, Alberta.

Grade 9 science classes from Bert Church High School are part of the 300 classrooms participating in Let's Talk Science's CurioCity Radi-N2 & You high school action project that was developed to engage Canadian classrooms in an experiment similar to Hadfield's Radi-N2. Over 7,500 students across Canada are completing the project alongside astronaut Hadfield and comparing their radiation results to Hadfield's data through Let's Talk Science's website.

Media are invited to attend the event.

Journalists who cannot be on-site will be able to watch the video connection portion of the event live on the CSA Website.
