How Does The Gm Tube Affect The Relationship Of Radiation

The experiment investigates a GM tube and a GM counter and the relationships of radiation. The experiment uses a GM tube to detect radiation coming from a source. This is done by the decay particle ionizing and causing the charge to build up in the tube, which is discharged and the discharge is counted by the counter and added to a display. The GM tube must be calibrated at the best voltage so that the count rate is independent of the voltage. A test was done to find this value by changing the voltage and taking the counts using radioactive source, the value was found to be 860 volts. The background radiation was found by having no sources of radiation involved and left the counter running, the value of background radiation was found to be (0.54±0.03) counts per second. The dead time of the tube was found by testing the tube with two sources separately and together, by comparing the counts found the dead time of the GM tube was found to be (325 ±6) μs. The final part of the experiment was investigating the efficiency of the GM tube, by comparing the real counts of the GM counter to the …show more content…
Though nuclear physics are perceived as dangerous due to their uses in nuclear weapons and the risks involved with nuclear power plants [1]. Radiation is not just an effect to be feared but is extremely useful and possibly necessary as society moves forward. Radiation is everywhere, but generally in such limited concentrations; the effects are negligible much like many chemicals which are harmless in small quantities and only dangerous in concentrated amounts. The experiment focuses on radiation and how a source of radiation is emitted and measured. The other main purpose of the experiment is to investigate how a Geiger Müller Tube (GM tube) in tandem with a Geiger Müller Counter (GM counter) works and how the mathematical relationships involved with the equipment work
