Wilson Cloud Chamber (Principle, Construction & Working)

Wilson Cloud Chamber

Wilson is 1911, invented a cloud chamber (called Wilson cloud chamber) to detect the presence of radioactive particles. To identify them and to measure their energy. Let us discuss the complete setup of Wilson cloud chamber. Principle: If we suddenly increase the volume of air saturated with water vapor, the temperature of air falls sharply and … Read moreWilson Cloud Chamber (Principle, Construction & Working)

Geiger-Mueller Counter Tube [G.M.Tube]

G.M Tube (Geiger Mueller Counter Tube) is a most useful of the instrument used for detecting and measuring the energies α, β, Ƴ, and X-rays. It is sufficiently sensitive to detect individual α and β particles. It is also used to compare the activity of the radioactive substance. Construction of Geiger-Mueller Counter Tube It consists of … Read moreGeiger-Mueller Counter Tube [G.M.Tube]

Proportional Counter : Nuclear Radiation Detectors

Proportional Counter

The proportional counter is used to detect & measure the energies of particles(α and β ) and also of photons. It operates under a potential difference across the electrodes which is such that the secondary ionization takes place but the output pulse is always proportional to the number of primary ions produced initially by entering … Read moreProportional Counter : Nuclear Radiation Detectors

Ionization Chamber : Nuclear Radiation Detectors

An ionization Chamber is used for detecting mainly the α and β rays and to compare the activities of the source emitting these rays. Construction of Ionization Chamber Basically, it consists of a chamber filled with a gas like air or argon at normal pressure it is fitted with a pair of electrodes E1 and … Read moreIonization Chamber : Nuclear Radiation Detectors

Gas-Filled Detectors : Nuclear Radiation Detectors

Hey, Once again welcome to Fullonstudy. In this post, we are going to discuss Gas-filled detectors in nuclear radiation detectors. Our last post is about Particle Detectors. Gas-Filled Detectors: When nuclear radiation passes through a gas enclosed between two electrodes, it ionizes the gas molecule. If a potential difference is applied across the electrodes the … Read moreGas-Filled Detectors : Nuclear Radiation Detectors

Particle Detectors : Nuclear Radiation Detectors

Nuclear radiation (or particles) such as α, β, and γ– rays cannot be observed directly. They are detected by secondary effects which they produce in the materials through which they pass. Effects based on Particle Detectors There are 3 such effects and a number of detecting instruments are based upon them. These effects are: Ionisation: A charged … Read moreParticle Detectors : Nuclear Radiation Detectors
