A scintillation counter measures ionizing radiation. The sensor, called a scintillator, consists of a transparent crystal, usually phosphor, plastic (usually containing anthracene), or organic liquid (see liquid scintillation counting) that fluoresces when struck by ionizing radiation. A sensitive photomultiplier tube (PMT) measures the light from the crystal. The PMT is attached to an electronic amplifier and other electronic equipment to count and possibly quantify the amplitude of the signals produced by the photomultiplier.

∙ 11y agoA scintillation counter is an instrument for detecting and measuring ionizing radiation.
It consists of a scintillator which generates photons of light in response to incident radiation, a sensitive photomultiplier tube which converts the light to an electrical signal, and the necessary electronics to process the photomultiplier tube output.
Scintillation counters are widely used because they can be made inexpensively yet with good quantum efficiency and can measure both the intensity and the energy of incident radiation.

∙ 13y agoIn very basic terms, a gamma counter (called a G-M tube or Geiger-Mueller counter) detects gamma radiation by means of measuring the electrical potential created inside the G-M tube due to gammas indirectly interacting with an electrode in its center. The G-M tube is filled with a gas and when a gamma interacts with the gas, the gas particle becomes ionized, releasing an orbital electron (e-). The e- is attracted to the positively charged electrode in the G-M tube and when it reaches the electrode, a voltage is induced. The change in voltage is picked up by the detector and is manifested as a "count" which is read out on the device's meter, usually in counts per minute (cpm).

Is B subtilis gamma hemolytic?
gamma/alpha hemolysis
What nuclear decay have no mass and no charge?
Gamma
Is Tyvek a gamma radiation blocker?
No, Tyvek is not a good gamma ray blocker. We know that Tyvek is HDPE (high-density polyethylene), and KDPE is a hydrocarbon. Even though it is "high density" material, it is only high density compared to other poly plastics. The best gamma ray blockers are materials with high mass. Atoms with high atomic numbers and high density are the ones we need to block gamma rays. Carbon and hydrogen don't fit the bill. Tyvek is a poor choice for gamma ray shielding. What is a good choice for gamma ray shielding? We might choose lead 'cause it's cheap and easy to use as well as a good gamma blocker. Certainly concrete and dirt work fairly well as we can get a lot of that stuff together to provide gamma shielding.
Define the terms antibody immunoglobulin and gamma-globulin?
Gamma globulins are a class of globulins, identified by their position after serum protein electrophoresis. The most significant gamma globulins are immunoglobulins ("Igs"), more commonly known as antibodies, although some Igs are not gamma globulins, and some gamma globulins are not IgsRead more: gamma-globulin
Is it possible for a Faraday cage to interdict a gamma pulse?
No. At least, I don't think it's reasonable to assume that. The reason it won't work is that, while a gamma ray is still an electromagnetic wave (just like a radio wave is), the wavelength of a gamma ray pulse is extremely short compared to the grid size of a Faraday cage, or even of the individual atoms.
How do you detector gamma?
Geiger counter
How a gm counter detect gamma rays?
Some Geiger counters can be used to detect gamma radiation. A better device for detecting gamma raysis a sodium iodide scintillation counter.
Do gamma rays really work?
YES,gamma rays will kill you.
How a geiger counter and gamma radiation can be used to measure the thickness of an object?
By using temperature
What is geiger counter used for?
A Geiger counter, also called a Geigerâ??Müller counter, is used for measuring ionizing radiation. A Geiger counter detects alpha particles, beta particles and gamma rays.
What geiger counter measure?
A geiger counter measures radioactivity. It detects the emission of nuclear radiation from alpha particles, beta particles, and gamma rays.
Does a Geiger counter detect gamma rays?
YES, but there are much more gamma sensitive detectors available such as Scintillation counters that contain a Sodium Iodide crystal and a photoelectric cells.
What willbe the expression for the work of cohesion between water and benzene?
Water and benzene will have a work of adhesion rather than a work of cohesion as this is the work associated with the connection between two things as opposed to cohesion which is the force holding one thing together. The expression for the work of adhesion is: gamma of the liquid vapour interface + gamma of solid vapour interface - gamma of solid liquid interface. Where gamma is surface tension.
What does Hans geiger's geiger counter detect?
the geiger counter detects radiation. when a radiation particle (alpha, beta gamma) goes through it clicks. the amount of clicking is how much radiation there is.
What specific property of nuclear radiation is used by the Geiger counter?
It detects the ions that are produced when radiation passes through an enclosed sample of gas.
Can a gamma ray be view with the naked eye?
Gamma Rays are Electromagnetic Radiation that cannot be viewed nor seen by the naked eye. Its properties can be observed though by various instruments such as a Gieger Muller tube/counter or a Cloud Chamber
Is there anything more reliable than a geiger counter?
There are good alpha and beta scintillation counters but the geiger counter is usually preferred and is highly reliable. It serves as a portable general purpose alpha, beta, and gamma detector.
