Abstrakt

We have formulated our problem from our wonders of why the researchers can’t agree on whether exposure from cellular telephones is carcinogenic. We have investigated the methods for the determination of SAR-values for cellular phones. We have thereafter analysed 2 contradicting experiments of three different types of researching: in vivo, in vitro and epidemiological studies, making a total of 6 experiments. Transgenic mice are used in the in vivo experiments and human cell tissue is used in the in vitro experiments as an approximate model for the human organism. The two epidemiological studies we have examined are a case-control study and a cohort study. We conclude by examination of the three different types of studies in general that the set up method for the experiment is of absolute importance. By our survey of epidemiological studies, we have found out that the possible occurrence of cancer is only detectable after a longer exposure period. The possible long term effects can’t be seen yet, because of the short existence of cellular phones. From our survey of the determination methods for SAR-values we discovered that these are primarily based on mathematical principles. We conclude that it is complicated to compare mathematical models with biological systems, because of the lacking knowledge of the biological complexity in general. All this is to be considered when deciding whether exposure from cellular phones could be carcinogenic.
