- ItemMeasurements of skin surface temperature during mobile phone use.(2007-01-16) Anderson, V; Rowley, JWe measured maximum temperature rises on the side of the face after 6 min of continuous mobile phone operation using two models of AMPS analog phones operating in the 835 MHz band and three early model GSM digital phones operating in the 900 MHz band For the GSM phones the highest recorded temperature rise difference was 2 3 degrees C and for the AMPS phones it was 4 5 degrees C both at locations on the cheek The higher differential temperature rise between AMPS and GSM may reflect the higher maximum average operating power of AMPS 600 mW versus GSM900 250 mW Additionally we compared temperature changes at a consistent location on the cheek for an AMPS phone that was inoperative 0 7 degrees C transmitting at full power 2 6 degrees C and in stand by mode 2 0 degrees C Our results suggest that direct RF heating of the skin only contributes a small part of the temperature rise and that most is due to heat conduction from the handset
- ItemMobile phones and brain tumours: a review of epidemiological research.(2009-02-25) Croft, R J; McKenzie, R J; Inyang, I; Benke, G P; Anderson, V; Abramson, M JThere has been a great deal of public concern regarding the possibility that the use of mobile phone related technologies might result in adverse health effects Corresponding to this there has been substantial epidemiological research designed to determine whether the use of mobile phones MP has any effect on health and in particular whether it increases the risk of developing head and neck tumours Such literature is particularly heterogeneous which makes it difficult to pool in a meta analysis This paper thus reviews the epidemiological literature pertaining to the use of mobile phones and mobile phone related technologies and head and neck tumours in an attempt to consolidate the various reports Although there have been individual reports of associations between MP use and tumours this research is not consistent and on balance does not provide evidence of an association There are reports of small associations between MP use ipsilateral to the tumour for greater than 10 years for both acoustic neuroma and glioma but the present paper argues that these are especially prone to confounding by recall bias The reported associations are in need of replication with methods designed to minimise such bias before they can be treated as more than suggestive
