СЕМ® ThermoDiagnostics personal thermograph is designed for measuring infra-red (IR) temperature of any surfaces. It is made in two modifications: without the software (with LCD screen) and equipped with software (with this version a user can get a color thermogram of an examined surface). Both modifications distantly receive IR emissions from remotely located objects, including skin surfaces. The device itself does not emit any irradiation during temperature measurements. Consequently, both modifications of the device can be used for measuring temperature without any restriction. The version of thermograph with software is linked with a computer through a radio channel. The channel frequency and irradiation power (not exceeding 10 mW/cm2) are allowed for use without any restrictions.

Today, almost everyone has a mobile phone. However, since it came into use, discussions over the degree of health hazard of this gadget still continue. Unlike other domestic appliances, while working, mobile phone is at immediate vicinity to brain and eyes. The majority of specialists think that the influence of radio magnetic emissions on human health depends on the power of signal and also on its ability to raise the temperature of tissues around it. During lengthy phone conversation any user can feel this effect through temperature raise in the auricle. Other organs, especially brain, are influenced by this adverse effect, and potential impairment of their functions may occur. Researches implemented by Russian and European scientists by using thermo vision cameras (http://www.radiostezija.lt/ru/) demonstrated the effect of local temperature rise in external ear and parotid areas in the range of 2,1 to 6,3°С. Consequently, the raise of local temperature in these areas with the following potential decrease (vasospasm revelation) indicates the change of vessel tonus, including brain vessels, which, in turn, may result in disturbances of local regulation mechanisms of cerebral blood circulation. |
