This was carried out by the Medical Devices Agency and is available on their website. I
understand that it was UHF transmission only that caused a problem, so emergency services
radios can be left on in hospital, but must not be used for transmission. Mobile phones cause
much less of a problem, but they do it even in standby mode, so these should be turned off.
