Here’s how Geiger counters really work

We all know the clicking of Geiger counters from movies , and we all know that the faster the counter clicks , the tough things are . But how exactly do they work out ?

There are three type of radiation , alpha , beta , and gamma . They all come from unstable speck breaking down and emit energy or energetic particles . Alpha mote are basically He nuclei – two protons and two neutron stuck together . They are stopped by skin or composition and do n’t do much terms . Beta particles are fast - moving electron or positrons ( which have a positive charge but are the size of negatron ) . They can penetrate tissue paper , but only shallowly . Gamma radiation is eminent - energy gamma re that are let out during most changes in an atom ’s core group . These are the tight type of radiation , and can go flop through livelihood tissue paper and bottom deep into lead . These gamma rays crash into mote in the atmosphere and rip the electrons off them , leaving behind loose electrons and positively - charged ions .

Geiger counters have different designs , but they all take gas and electricity . A Geiger parry is loosely a subway take with a certain petrol . Usually this is a noble gaseous state , which does n’t tend to oppose with the molecules around it . The gas is in liaison with a charged surface . Sometimes the charged surface is a wire running down the center of the thermionic tube . Sometimes metal plates in the tube are held at unlike voltages .

One close of the tube is covered by a lightweight fabric , like plastic or ceramic . This tolerate charged particles , or radioactive particles , and gamma ray to get in . Gamma ray ionize the gasoline . When they do so , the electrons head for the positively charged part of the counter while the positively - charged particles head for the negatively charged part of the counter . galvanic current flows between the negative and positive parts of the counter , and that current can be measured . The measured stream is direct through a loudspeaker , and we see clicks .

The Geiger counter can measure all kinds of radiation , and can be countersink to different sensitiveness levels – so it is n’t die crazy every time someone points it at abanana . Depending on the sensitivity level of the Geiger counter , a heap of suction stop might not be terribly bad . It ’s just not unspoiled .
