III. Read and translate the text: “CELLULAR TELEPHONE AND SAFETY OF HEALTH”

For the last year the telephone has turned to a usual working tool what it should be from a toy and a measure of richness. Cellular phones are used practically by everybody and it is possible to hear the bell of a cellular phone almost anywhere. So telephones often ring on performances and even more at cinemas and that is to my mind a disadvantage of the owner’s education. In the city center you can notice much more than ten cellular phones people passing by have. First of all, such availability is connected with constant lowering of handset’s cost and certainly significant lowering of cost a minute talk for cellular operators. The army of the mobile telephone users is enlarged regularly and those who have the telephone for a long time today can allow themselves to speak longer but for the same money they had to pay two of years ago. The main question of this article is whether the cellular telephone is so safe that we think.

On the World-wide Organization of public health Services has published the recommendations on safety cellular telephones in connection with forthcoming conference of the European parliament. It was marked that for today there are no convincing proofs about link of usage of mobile telephones with development cancer or other serious diseases. The final outputs are supposed to be made by results of long-term research in 10 countries of the world, which completed in 2004. The negative effects like deceleration of response time or disorders of dream are not confirmed scientifically. It is indicated in recommendations that any special security measures in relation to cellular telephones shouldn’t be taken.

The data obtained by the group of scientists from Canada researching the influence of irradiation by radio waves (from antennas of cellular communication placed on roofs of buildings and from cellular telephones themselves) on the man’s health correspond to the given research. Their independent research was carried out on inquiry of the Ministry of public health services of Canada and it was marked that “the irradiation (radio- frequency fields) that type and intensity which is formed by devices of a radio communication don’t promote appearance or development of growth for animals or people”. Despite of it, the necessity of improving the Canadian laws was marked in the problems of protections of staff operating in the field of a cellular transmission. The research of level of radiation from antennas of cellular communication located on the roofs of buildings was carried out 118 objects in 17 towns. The main objects of research were school buildings in the places were the population showed maximum concern on this question. In result the commission found that on all objects the level of radiations inside buildings was much lower than extreme valid values both on international standards. Essentially the schoolchildren inside buildings receive a smaller doze of irradiation than outside on distance 300 from the antenna.
