In this experiment you will explore the penetrating power of different types of radiation. A Geiger counter is used to measure the radiation coming from four different radioactive sources, which can be selected by rotating a turntable. A second turntable can be used to place four different types of absorbers between the radioactive source and the detector.
The further you are away from a radioactive source, the better! This experiment will demonstrate how the amount of radiation decreases with increasing distance from the source. A Geiger counter is used to measure the radiation coming from a real radiation source at a distance selected by you.
Katika jaribio hili utachunguza nguvu ya kupenya ya aina tofauti za mnururisho. Geiger counter ni kipimo cha radiation kutoka kwa vyanzo vinne tofauti vya radioactive, ambayo inaweza kuchaguliwa kwa rotating turntable. Turntable pili inaweza kutumika kuweka aina nne tofauti ya absorbers kati ya chanzo cha mnururisho na detector. Kadiri ulivyo mbali na chanzo cha mnururisho, ndivyo inavyokuwa bora zaidi! Jaribio hili litaonyesha jinsi kiasi cha mnururisho unavyopungua kadiri umbali kutoka kwa chanzo unavyoongezeka. Geiger counter ni kipimo cha radiation kutoka kwa chanzo halisi cha radiation katika umbali unaochaguliwa na wewe.
