We all, surely, seek to look after health and safety of our family, relatives and friends, especially in the conditions of modern life, rapid development of new technologies, and degraded state of ecology We began to think about that more often! People constructed plenty of instruments that assist in solving these tasks. But are we always aware of danger?! Lots of people dont even suspect that they should take care of personal radiation safety, as we cant feel, see or comprehend radiation any other way!
Logical question arises: how then can I make sure there is no radiation present? Its as easy, as ABC! For this purpose there is a Ukrainian household dosimeter TERRA-P from Ecotest trade mark. Its development was stimulated by a large number of appeals from average citizens willing to buy a radiation detector for everyday use of high-quality and at a reasonable price.
Its not a strange thing for population of a country, where one of the most disastrous catastrophes of the planet took place, the consequences of which we still experience. Today, 15 nuclear power units are operating in Ukraine now and then being the source of alarming rumors about dangerous radio-ecological situation in their vicinity. But, unfortunately, if we simply avoid being near nuclear power plants, it wont help us fight radiation impact. It can be everywhere: in foodstuff, construction materials, in different harmless trifles of our life etc. Thats why we should always have sufficient information at hand about things surrounding us.
Now its possible with the sixth sense organ that will on the fly (within 10 seconds) help to learn about the presence of radionuclides in mushrooms, berries, vegetables, or, for instance, in a picture inherited from parents. The dosimeter will come in handy not only on the territories near NPP and in industrial areas, but also be of use for those, who decided to build a house, buy a car, or inspect for radiation level of own workplace or a place of resort.
By the way, TERRA-P dosimeter is based on the professional dosimeter-radiometer TERRA used as the armament for the Ukrainian army, and enjoys popularity among many different countries of the world. The household model with built-in clock and alarm clock is light, compact, easy-to-use, with ergonomic design, and is intended to control gamma and beta radiation types.
TERRA-P dosimeter is used to:
* Check for radiation pollution:
- of foodstuff
- at purchase of real estate
- of construction materials
- of places for building construction
- of places after Chornobyl accidents
- of suspicious items
- while traveling
- when hunting, fishing
* The MKS-05 TERRA-P dosimeter-radiometer is recommended by the Ministry of Education of Ukraine for use in educational process in secondary schools (Protocol # 440 of June 7, 2001)
