None of t he st udies dem onst rat ed t heexist ence of any har m ful healt h effect s from wireless phones RFexposures. However, none of t he st udies can answer quest ions aboutlong- t erm exposures, since t he average period of phone use in t hesest udies was around t hree years.W ha t r e se a r ch is ne e de d t o de cide w he t he r RF e x posur e fr omw ir e le ss phone s pose s a h e a lt h r isk ?A com binat ion of laborat ory st udies and epidem iological st udies of peopleact ually using wireless phones would provide som e of t he dat a t hat areneeded. Lifet im e anim al exposure st udies could be com plet ed in a fewyears. However, very large num bers of anim als would be needed t oprovide reliable proof of a cancer prom ot ing effect if one exist s.Epidem iological st udies can provide dat a t hat is direct ly applicable t ohum an populat ions, but t en or m ore years' follow- up m ay be needed t oprovide answers about som e healt h effect s, such as cancer. This isbecause t he int erval bet ween t he t im e of exposure t o a cancer- causingagent and t he t im e t um ors develop - if t hey do - m ay be m any, m anyyears.
