This article concerns the sources of non-ionizing radiation in a normal inhabited environment. Measurements show that residents are exposed to non-ionizing radiation in levels both below and above the European normative. Excess is present due to the fact that, producers of electronic equipment and appliances, those who use them, as well as those involved in the construction of housing, have insufficient acquaintance with non-ionizing radiation. Producers are advised to increase the coefficient of safety towards non-ionizing radiation by renewing technology. Users are advised to operate apparatus with the lowest possible power, to minimise time exposed to sources, to maximise the distance from them and to renew their appliances. Construction workers should take non-ionizing radiation more into consideration when furnishing of houses.
Rapid development of science and technology is associated with a necessary contaminant: non-ionizing radiation.
This article treats the following areas: the wave nature of non-ionizing radiation, its spread in the electromagnetic spectrum, the physical quantities and units by which non-ionizing radiation can be measured [1-6]. An attempt is made to supply the public with essential and sufficient knowledge of non-ionizing radiation present in their homes (including internal and external types of sources, models, their power as well as invisible sources). With the results of measurements of non-ionizing radiation within their dwelling places, they might judge to act and to suggest to people who deal with projecting and furnishing the houses, with frequent renovation of technology in order to reduce the non ionizing radiation and to avoid as much as possible the exposure to it [3,4,6,7].
2. MATERIALS AND METHODS
1) Materials that are used: field meters up to 300 MHz and up to 3 GHz, an inhabited apartment available in the city of Gjirokastër.
2) Experimental method is applied by direct measurement.
3. THE WAVE NATURE OF NON-IONIZING RADIATION
(for more see 8) [1-6].
4. SOME PHYSICAL QUANTITIES AND THEIR UNITS BY WHICH NON-IONIZING RADIATION IS VALUED
(for more see 8) [8,9].
5. SOURCES OF NON-IONIZING RADIATION IN A NORMAL HABITATION
A normal inhabited apartment is selected for this work (AP.3 figure 1).
6. MEASUREMENTS OF NON-IONIZING RADIATION [7,8,10]
The measurements are done in Apartment 3 of the Block behind the Sports Palace, “18 Shtatori” neighbourhood, Gjirokastër, Albania.
6.1. Measurements
1) The level of non-ionizing radiation of external sources of high frequencies is B = 0.059 μΤ.
2) The level of radiation of sources of internal environment is as in tables 1 and 2.
