ence of the radiation level between new and old technology. The radiation level of the a flat screen TV set produced in 2008 with 75 W power is 0.56 μΤ less than the one with cathode tube with the same 75 W power produced in 2005.

Table 2, the measurements 15, 16 and 17 show the difference in radiation levels of three mobile phones with different technology. The magnetic induction of the phone produced in 1992 was 0.667 μΤ (the normative is 0.45 μΤ), the one produced in 2000 had the magnetic induction 0.118 μΤ and the one produced in 2005 had the magnetic induction 0.012 μΤ. The difference between the first and the last one is 0.615 μΤ.

Table 1, measurement 17 shows the use of a stabilizer with 5000 W power near a computer which at 0.2 m distance has a radiation of B = 1.668 μΤ (1.168 μΤ above normative). Buying a stabilizer of this power is unnecessary. One with 1000 W or even less is sufficient. Another stabilizer of 1000 W (table 1, measurement 16) was near a TV set which at a distance of 0.2 m had a radiation B = 0.338 μΤ. The position of the user was 0.5 m away from the 5000 W stabilizer and 5 m away from the 1000 W stabilizer.

The above mentioned stabilizers should have been in different positions and distances. The one with a higher power (5000 W) placed near the TV set should have been 5m away from the viewer and the one with less power (1000 W) placed next to the computer should have been 0.5m away. However such changes were not made due to lack of knowledge.

In figure 1, several objects exposed in space and time are selected:

• The adult’s bed A;

• The children’s bed B;

• The sofa C;

• The sofa D.

The adult’s bed A is exposed to radiation from:

1) The 220V electric line which goes underneath it and according to measurement 19, table 2, is E = 20 V/m and B = 0.4 μΤ;

2) The baby phone (receiver), no. 22 in legend, according to measurement 8, table 2, is E = 97 V/m and B = 0.23 μΤ;

3) The devices with legend numbers 6, 7, 8, 9, 10 placed behind the separating wall according to respective measurement 6, 1, 2, 3, 7, table 1, are E = 19 V/m, B = 1.16 μΤ; E = 7 V/m, B = 3.01 μΤ; E = 2 V/m, B = 9.28 μΤ; E = 6 V/m, B = 0.18 μΤ; E = 12 V/m, B = 0.4 μΤ.

The adults’ bed should be next to the opposite wall in order to avoid this exposure, but it is not because of lack of knowledge.

The children’s bed is exposed to the radiation of:

1) The 220 V electric line which goes underneath it and according to measurement 19, table 2, is E = 20 V/m and B = 0.4 μΤ;

2) The multi socket with legend no.23 according to measurement 18, table 2, is E = 20 V/m and B = 0.4 μΤ;

3) The baby phone (transmitter) with legend no. 18 according to measurement 7, table 2, is E = 91 V/m and B = 0.24 μΤ;

4) The Internet antenna with legend no. 26 according to measurement 13, table 2, is E = 11 V/m and B = 0.2 μΤ (while the respective normative are 137 V/m and 0.45 μΤ);

5) The devices of the neighbouring apartment (AP.1) with legend no. 1, 2, 3, 4, 5 placed behind the separating wall according to respective measurement 1, 2, 3, 7, table 1, are respectively E = 7 V/m, B = 3.01 μΤ; E = 2 V/m, B = 9.28 μΤ; E = 6 V/m, B = 0.18 μΤ; E = 12 V/m, B = 0.4 μΤ.

It was difficult to change the position of the children’s bed because of the inappropriate house plan. Even when the inhabitants were told that they were exposed to the radiation of the devices in the neighbouring apartment, with legend no. 1, 2, 3, 4, they were indifferent and made no changes.

The best opportunity to prevent the bed from being exposed to the radiation emitted by these devices was available to the architect of the building, who should have taken into consideration the opposite wall (AP.1) when planning the layout of the building.

The children’s bed could be protected from the internet antenna radiation, with legend no. 26, if the signal from the modem to the computer, with legend No. 18, were done with a cable.

The sofa C is exposed to the radiation from:

1) The multi socket with legend no. 25 according to measurement 18, Table 2, is E = 31 V/m and B = 0.6 μT;

2) The devices in the neighbouring apartment (AP.2) with legend no. 13, 14, 15, 16, 17, placed behind the separating wall, according to respective measurements 4, 7, 3, 2, 1, table 1, is respectively E= 13 V/m, B = 1.07 μΤ; E = 12 V/m, B = 0.4 μΤ; E = 6 V/m, B = 0.18 μΤ; E = 2V/m, B = 9.28 μΤ; E = 7V/m, B = 3.01 μΤ;

The sofa D is exposed to the radiation of:

1) The devices of the neighbouring apartment (AP.1) with legend no. 17 according to measurement 1, table 1, is E = 7 V/m, B = 3.01 μΤ;

2) The electric fuse box of voltage U = 220 V according to measurement 1, table 2, the intensity of the electric field (E) varies between 29 V/m and 199 V/m and the magnetic induction (B) varies between 0.49 μΤ and 2.03 μΤ.

The living room where the sofas C & D are placed has no other possibility for the furnishing. Again it was the responsibility of the architect to plan, beginning in his design project, the electric devices 13, 14, 15, 16, 17 on the wall opposite the apartment and the fuse box next to the apartment intercom with legend no. 20.

7. CONCLUSIONS

Based on the above measurements we can draw the respective conclusions:

1) The less electronic apparatus and appliances an environment has, the less a person is endangered by nonionizing radiation.

2) The passing of the electric lines should be placed away from areas which the inhabitants stay for long periods of time (such as places for beds, sofas etc)

3) The producers of electronic apparatus and appliances should raise the security coefficient towards nonionizing radiation and the users should be careful to replace over time apparatus of old technology with those of new technology.

4) The sources of non-ionizing radiation should be placed as far away as possible from areas which the inhabitants stay for long periods of time.

5) Apparatus with low power should be chosen as much as possible.

6) The users of electronic equipment and appliances should decrease as much as possible the exposure time during work.

7) The inhabitants, while furnishing their houses, should pay attention to the sources of non-ionizing radiation in their homes as well as in neighbouring houses.

The architects should “arrange the relation to” nonionizing radiation while planning dwelling places.
