Is it safe to use a mobile in hospital?

The Medicines and Healthcare products Regulatory Agency (MHRA) says that mobiles are part of everyday life and that their use needn’t be unduly restricted in hospitals. The advice is that phones are safe to use in most areas, but there is evidence that they can interfere with some critical clinical equipment and should be switched off in areas like intensive care. Now that most phones have cameras, the other concern is privacy. Hospitals discourage photography, especially in the ward areas.
