So that the office space of polonium, apparently just begun. A start has been good. The radioactive isotope polonium-210 was a fuel "stove" is installed on -2. Night of the Moon is very long and cold. Over 14.5 Earth days lunar rover is at a temperature below -130 C.

But in the instrument container, all this time was to keep the temperature that is suitable for sophisticated scientific equipment. Polonium heat source was placed outside the instrument container. Polonium emits heat continuously, but only when the temperature in the instrument compartment fell below the required limit, the exchange gas, heated polonium begins to flow into the container. The rest of the excess heat is dissipated into space. Atomic oven 2 features full autonomy and absolute reliability. There are, however, the polonium-210 and restriction. Relatively low half-life – just 138 days – puts a natural limit to life radioisotope sources with polonium. Please visit doppler labs if you seek more information. Similar devices are used on Earth.

Apart from these, are important Polonium-beryllium and polonium-boron neutron sources. This sealed metal capsules, in which lies covered with polonium-210 ceramic pellets of boron carbide, carbide or beryllium. Flux of neutrons from the nucleus of an atom boron or beryllium generate alpha particles emitted by polonium. These neutron sources are light and portable, completely safe to work, very reliable. Brass ampoule 2 cm in diameter and a height of 4 cm – Soviet polonium-beryllium neutron source – every second gives up to 90 million neutrons. Among other worldly affairs element number 84, probably should mention its use in standard electrode alloy. These alloys are needed for ignition spark ignition internal combustion engines. Emitted by polonium-210 alpha particles lowers the voltage necessary for the formation of a spark, and therefore, facilitate the inclusion of the engine. Safety precautions when working with polonium have to be very careful. This is probably one of the most dangerous radioactive elements. Its activity is so great that, although it emits only alpha particles, can not take his hands, the result will be the ray skin lesions and, possibly, the whole body: Polonium quite easily penetrates through the skin. Element number 84 is dangerous and at a distance exceeding the length of the path of the alpha particles. He is able to move quickly into aerosol state and contaminate the air. Therefore, working with polonium in a sealed boxes, and the fact that radiation from polonium is easy to defend, it is extremely beneficial for anyone who has to deal with this item. The attentive reader has probably already noticed that in this article, wherever referred to the practical application of polonium, where only one isotope – to a mass number 210. Indeed, other isotopes of the element number 84, including the most long-lived polonium-209, has not gone beyond laboratory. However, many scientists believe that the cosmic energy is promising, and polonium-208, also a pure alpha-emitter. The half-life had significantly greater than that of polonium-210 – 2,9 years. But as long as this isotope is almost inaccessible. How long will he walk only in the future, the future will show.
