No. A GM tube only counts the ionizing events that happen to interact with it. Consider that a radioactive source radiates in 360 degrees, in three axes, to form a three dimensional sphere of radiation. The GM tube intersects only part of that sphere and, even for the the parts that do intersect, its not always a direct intersection, so there is not always a capture of an event that registers on the tube. This is why we talk about calibration geometry and efficiency.

What are some naturally occurring ways we receive radiation?
I assume you mean ionizing electromagnetic radiation. Cathode ray tube televisions (i.e. the non-flatscreen televisions) and some other electric devices produce some radiation. While it might sound pretty excessive all these sources add up to a very small amount of radiation. About 2.4 mSv. Most additional radiation people receive are from medical imaging methods such as a CT-scan (20 mSv)
Do all molecules absorb infrared radiation?
No all molecules do not absorb infrared radiation. Some of them do.
Does solar radiation contain a complete spectrum of all forms of electromagnetic radiation?
Yes it does. It contains all the forms of radiation, but 99% of its energy is carried by radiation with wavelengths between 278 and 4600 nm, with the maximum at 4720 nm.
What percent of radiation is absorbed?
The radiation that are absorbed are not all useful. Only the harmful ones are.
Is radiation heat?
No... radiation is the movement of waves and particles, and influence of movement upon all other matter around it or in it's path... What happens though, is that it causes (excellerates) the atoms in any material it encounters (and that material becomes hot, the greater the radiation, the greater and more violently it will be heated)...
How do you use the geiger muller tube to test for alpha?
Do you want to verify that a radioactive source emits ONLY alpha particles? If so, first measure the original count-rate, with no radioactive source, on the GM-tube. This is the background count-rate. Next, place the radioactive source near the GM-tube, and measure the new count-rate. Place a thin piece of paper between the GM-tube and the source. You will see that the count-rate dropped to the background count-rate. This is because all of the alpha particles are absorbed by the paper. If there were other types of radiation, like beta and gamma radiation, the count-rate wouldn't drop to the background count-rate.
What are the methods of detecting nuclear radiation?
Radiation energetic enough to ionize matter with which it collides is called Ionizing Radiation. The Geiger counter is a radiation detection device that makes use of ionizing radiation in its operation. This device is also used to measure the amount of radiation.
Does it matter if aluminum absorbers are near a Geiger-Muller detector when you have a radioactive source of beta particles?
It does if you want to detect the beta radiation. Beta radiation, beta particles, can be stopped with a sheet of aluminum foil. An aluminum "absorber" would act as a shield to the Geiger-Müller (GM) detector and stop the beta radiation, which is really high energy electrons or possibly positrons. Placing a shield between the source of the beta radiation and the GM detector would block the radiation, thus shielding the detector from it. The detector would be "blind" to the radiation. Note that this would be effective if all you wanted to do was look at gamma rays. The gamma rays and the beta radiation would leave the source and head to the GM detector, the beta particles would be blocked by the aluminum, and only the gamma rays would make it to the GM tube to be counted. Links can be found below.
Why should gamma rays be detected at a point within the Geiger-Muller tube rather that at the end of it?
Let's look at the construction of the tube. The Geiger-Müller (GM) tube is essentially a cylinder with a "wire" down the middle for an anode, and the inside of the cylindrical housing as the cathode. It's got some gas in it, and the type of gas will vary a bit from tube to tube and what is desired in the design. The "end" has a "window" in it made of thin glass or possibly mica. This window "lets in" the radiation while sealing the tube and providing a minimum amount of shielding that might "block" radiation, particularly alpha and beta radiation. Recall that alpha particles are helium-4 nuclei, and they can't penetrate a sheet of paper. Beta particles are high energy electrons, or possibly positrons, which can be stopped by a sheet of aluminum foil. You can't detect them if you block them. The way it works is as the radiation passes through the GM tube, it leaves an ionized "trail" in the gas behind it. This is primary ionization. The high voltage across the gas causes the ions to be accelerated toward the appropriately charged element. Positive charges move toward the cathode, and negative charges (electrons) move toward the anode. The movement of these charges ionizes other gas atoms, called secondary ionization, and the total effect is to create a current avalanche. With the movement of these charges and the accompanying current "spike" or "jolt" set off by the high voltage, we'll observe a "pulse" that the supporting circuitry in the detector can "see" and a "hit" or "count" is recorded by the Geiger counter. Gamma rays are penetrating types of (electromagnetic) radiation. They blast through the window and they ionize the heck out of the gas inside. It is basically the cumulative effect of all this ionization that creates sufficient ions to initiate the current avalanche that cause the counter to "pulse" electrically. The gamma rays have a field day zapping their way through the cylinder and creating lots ions to create a "click" or a count. In contrast, alpha and beta particles will not penetrate very far into the tube because of their limited ability to do so. This means that the current avalanche is more confined to the "front" of the tube. The superior penetrating power of the gamma rays means that their current avalanche includes a lot of volume deeper in the tube, or more "in the middle" than at the end of the tube, like the particulate radiation. Links can be found below for more information.
Which radiation detector is independent of particle A- wilson cloud chamber B- GM tube C- solid state detector D- all?
The Wilson Chamber has the radiation independent of the particle. This is a particle detector used for detecting ionizing radiation.
Where do nuclear decay occur naturally?
Radioactive Decay occurs naturally all around us. If you test for radiation with a Geiger Counter, you will find that it picks up radiation in the air around you. Mostly, however, radioactive decay occurs in the earth's crust. I cannot name a specific element, as there are many that decay.
Was Emily Geiger married?
Emily Geiger did not marry Teddy Geiger at all, im sure of that. She married John Threewits.
What causes the development of the geiger counter?
Necessity is the mother of all inventions.
What is radioactive noise?
The ground has small amounts of radioactive elements which means they emitt alpha rays, beta rays & gamma rays. Some locations have more then others but there's a little just about everywhere. There are also radiation particles that come from outer space (cosmic rays). All of these radiations are called the "background" radiation and can be counted with a Geiger counter. When a scientist is trying to do an experiment in radioactivity the background radiation is called radiation noise because its really not wanted and can interfere with the experiment.
Where is the best place to get Kurt Geiger discount codes?
From my experiences, there are many source to get Kurt Geiger promo code on the Internet. However, among them, I highly recommend Couponsohot.com - a coupon site lists all available deals from many famous store, including Kurt Geiger
When was All About Radiation created?
All About Radiation was created in 1957.
Do you have to wear a lead shield when you get x-rays at doctors?
Yes. X-ray radiation can cause all kinds of nasty side-effects, such as cancer and lowered sperm count.
