The Village hired Paul Muntuk from Interior Radium Pro Services to test the Kaslo library space for radon from February 2 to March 6 of 2017 . On April 4, the Board received the results and a recommendation to cease operations by the Village. The average radon concentration in 8 locations ranged from 311-359 Bq/m3. For values between 200-600 Bq/m3, Health Canada advises to take remedial action within 2 years. Health Canada also recommends radon testing for at least 3 months during winter for accurate results.
Library users and volunteers do not spend enough hours in the library for these radon levels to pose a health risk. Steps may be taken to reduce risk for staff who receive a radon dosage that is above the recommended maximum of 1 mSv per year by improving ventilation. The board is actively seeking solutions to implement. Please read the following documents and explore the links for more information about radon in the library and radon in general. Check back for updates.
The Village of Kaslo as owner will be in charge of permanent mitigation steps. Unfortunately the renovation of the upper stories prevent such steps being reasonably and properly planned and undertaken until completion next year. The Library as tenant will be undertaking all reasonable steps to mitigate the radon during this year. An openable window has been installed in the office, further natural ventilation will be studied, as will an air to air heat exchanger for winter ventilation, utilizing the present HVAC system to increase air exchange. The library and the Village will be cooperating during temporary and permanent mitigation undertakings.
