Traditionally, DECT cordless phones emit high levels of EMFs. The base unit transmits all the time, whether the phone is in use or not, and the handset transmits at full power when in use, regardless of how far the handset is from the base unit. For people who are electrosensitive, or those who wish to take a precautionary approach towards EMFs, clearly this is not a good thing! If you ARE electrosensitive, then a cordless phone of any variety is unlikely to be suitable.
