Elisabeth Cardis, Leiterin der Interphone Studie und Siegal Sadetzki, verantwortlich für den israelischen Beitrag zu Interphone, raten bei Handynutzung zur Vorsorge.

Im neuesten BMJ Journal of Occupational and Environmental Medicine ist die Arbeit der beiden veröffentlicht. Aus dem zur Verfügung stehenden Abstract geht nicht all zu viel hervor und mehr gibt es nicht dazu.

Powerwatch weist auf diese Arbeit hin und zitiert daraus.

Simple and low-cost measures, such as the use of text messages, hands-free kits and/or the loudspeaker mode of the phone could substantially reduce exposure to the brain from mobile phones.

Therefore, until definitive scientific answers are available, the adoption of such precautions, particularly among young people, is advisable.

While more studies are needed, indications of an increased risk (of gliomas - a particularly dangerous form of brain tumour) in high and long-term users from Interphone and other studies are of concern. ... Even a small risk at the individual level could eventually result in a considerable number of tumours and become an important public-health issue.

Elizabeth Cardis led the Interphone study for IARC/WHO; Siegal Sadetzki led the Israeli study. These are two world-class leading researchers into the causes of cancer.

They have produce a balanced and considered over-view of the science so far and their conclusions are given in the box above.

They note that in the Interphone study the median totalled lifetime use was around 100 hours, which represents just over 2 hours of cellphone use per month. Most users, including many children, now exceed this level of use. Even the highest exposed group (1640 total hours or more) averaged only about 27 min of phone use per day. Further studies analysing the amount and duration of use are therefore essential.

They note that in Interphone, started in 2000, the maximum duration of use among the study participants was about 12 years, and only 5 years had passed from the start of heavier use. For most known carcinogens, however, identification of increased risk of solid tumours (particularly brain tumours) has required long follow-up periods of subjects with substantial exposure. For example, while the atomic bombs were dropped on Hiroshima and Nagasaki in August 1945, an excess risk of solid tumours was reported in the survivors only in the 1960s, and no elevation in risk of brain tumours was noted for about the first 50 years.

Da Powerwatch auch zur typischen mobilfunkkritischen Dramaturgie neigt, bin ich deren Interpretation gegenüber noch etwas vorsichtig, bis vielleicht eine andere Quelle zur Verfügung steht.

Allerdings sind beide Wissenschaftlerin bekannt dafür, dass sie im Gezerre um die Interpretation der Interphone Ergebnisse dem kritschen Lager angehören.

Ihre Vorsorgeempfehlungen richten sie wohl verstärkt auch an Kinder. In Deutschland scheint die Handynutzung durch Kinder eher noch gemäßigt zu sein. In England sieht es da ganz anders aus. Dort soll über die Hälfte der 5 bis 7-jährigen Kinder ein Mobiltelefon haben und 75 % der bis zu 10-jährigen.
