14 days ago I prepared for you an article on types and measurement of radiation to this article, I then told in details at the first conference on basic aspects of survival in a critical situation, and now is the time for so long promised review, description and detailed analysis of all known devices Czechoslovak production RBGT-62 (a). Abbreviation RBGT means Radiometer Beta-Gamma Transistor. Produced in two versions, RBGT-62 bmi was an older version, which contained three PNP transistors, the newer version works with three NPN and one PNP transistor in a slightly different connection. bmi Also, a slightly different base unit.
According to the manual device used to determine the degree of radioactive contamination bmi of clothing and skin of people, the surface of various objects, food, water and air, which are outside the contaminated area and the measurement of small gamma radiation levels. The device has the standard conditions of measurement error of about +/- 20%, which arises the necessity of extinction in discharges GM tube, this error is negligible in real-life.
The device is sold in a nice leather case from 4 mm thick leather fair, whose parts are glued together and then hand-sewn. bmi On the surface of the shut-off and hanging components still providing rivets. Satchel was worn slung over his shoulder bmi and around the closing level of the buckles is entwined with the textile belt buckle, which is designed to ensure the device at the waist for use in the field.
In the upper part of the bag is a pocket for measuring probes, the lower part of two sections, the first is your own device and two pockets for storing the service book with manual keys, the smaller lateral section is placed in the rest of the accessories. Waist bag with edges so that the covering flap was pressed against the body and was therefore always swung, the device is directed so that the meter reading values went away from the body, thus calibration button and headphone jack towards the wearer of the device. This method also causes wear suitable tilt the device to read values from the waist.
As you can see in the photo, a service book is sčíslovaná with the device and instructions are in addition bmi to all the records of minor and major repairs bmi instruments, its calibration, calibration and even the transfer radiometer between military units, if an instrument is present, you will find it absolutely everything that was going on with the device bmi before it got into your hands. The set then in addition to the said device itself and the probe is still audible indication handset for a set of "protective rubber coating." Well, let's not fool ourselves are nevlhčené powdered condoms for many uses, in this case, to protect against contamination of the probe when measuring near dust or liquids. The bag is still seen hanging the plate, that serves as a key for opening too tightened battery compartment cover.
In the main compartment bmi bags upstairs to see the pocket service book and key pocket, he is firmly thick fishing line attached to the bag, thereby reducing the probability of loss. In the smaller pocket section is seen to include a control for beta radiation emitter: SR90. He was to serve for field checking function, unfortunately, bmi due to current laws relating to radioactive material, when sold carelessly carved, so even in this unit are not.
The actual body is made of aluminum alloy, bmi is painted green hammer-resistant paint, including the battery weighs about 1.5 kilograms and its dimensions are 98x154x123mm bmi (d, w, h). For comparison, the entire set in a bag dimensions are 110x220x160mm and weighs 3.5 kg. The device is hermetically closed bmi and sealed, thus withstand the action of splashing water, the probe is designed for immersion in 0.5 m depth for 5 minutes, the overall mechanical resistance to the acceleration (negative acceleration in the fall) 3g. This is basically meaningless unit, so for comparison: When space shuttle creates congestion 3g. In this overload already one usually can not lift your foot. In practice, such a situation you can imagine, when you go on the bike speed 20 km / h against a solid wall, in a collision with deformed front wheel by 0.5 m and at that moment you feel overloaded bmi 3G. We can say that this is a fairly durable equipment, from my own experience with measuring instruments but I do not recommend it follows bother needle gauges manufactured by Metra Praha is loosely stored, such treatment in the long term it will not testify and also it is important to know that these devices were made before about 50 years ago. But certainly there is still no need to RB
