The Geiger Counter

Its very hard to get your hands on a decent Geiger counter. After the disaster in Japan they have all shot up in price. The cheapest good one is between 80-160 pounds. There are many ways of making your own Geiger counter with buying anything which i will do soon. But these will be very basic and not be very reliable. Buying a kit would be good as it would be efficient and not too expensive but you will need to assemble all the part which is hard and if done wrong, the damage will be irreversible! Luckily I have found a slightly damaged but efficient and cheap one that i will buy and use along side my homemade one. 

This is it, I believe it comes with a English sticker though.

Here is the simple homemade one I shall make using only a multimeter , Battery, Tin can, wires, transistor and a resistor.
