If helium is small enough to get in a watertight phone, it is certainly small enough to dissipate in a probably not so watertight building.

- warrenm 8y agoNot true - the whole point of burst discs etc in MRIs is so that if a quench happens, the patients and any technicians in the room survive Venting even a full MRI's worth of LHe (~1500l) as most will make you a little lightheaded for a few minutes The risk of death from quench events is effectively non-existent
