Nobody Sneeze
Technician Pooja Woosaree, '14 BSc(Spec), works in the low-radon clean laboratory at the U of A's Centennial Centre for Interdisciplinary Science, where astroparticle physics researchers build and test highly sensitive neutrino detectors. Radioactive radon and dust interfere with the ability to observe neutrinos, so constructing the detectors in a sealed and filtered environment - with radon levels less than one per cent of those in normal air - is vital to the research of these elusive subatomic particles.
