It depends on the usage.

A proportional counter operates in the linear region, meaning that the amplitude of the pulse is proportional to the energy of the captured ionizing event. Integrating the pulses yields an estimate of the total energy in the field, which is related to dose rate.

A geiger counter, on the other hand, operates in the avalanch region, which means that every ionizing event yields the same amplitude pulse. You lose the ability to estimate dose rate, but you gain sensitivity. The advantage is the ability to quantify, though not qualify, contamination levels.

Why a geiger counter gives a lower counting rate for radioactive material that has a long half life than does with short half life?

A Geiger counter detects radiation by counting the number of decay events that occur. Radioactive material with a long half-life decays more slowly, resulting in fewer decay events per unit time compared to material with a short half-life. Therefore, the Geiger counter will record a lower counting rate for radioactive material with a long half-life.


Is a geiger counter better than a bubble chamber?

Neither is better. They are used for different purposes. Geiger counters detect rates of beta and gamma radiation, emitting clicks as they are detected. Some types can detect alpha particles also. They are used as devices in the field, to determine such things as safety of an object or place. Bubble chambers also detect ionizing radiation, but they do so by recording, rather than rates of emission. They have historically been used for research, though they are used less now than they have been in the past.


Why does Geiger counter not truly measure alpha radiation?

Alpha particles are Helium nuclei, two protons and two neutrons - mass 4 and charge 2. These particles have very little penetrating capability - they can be stopped with a few inches of air, a sheet of paper, your skin, etc. As a result, alpha particles have no chance of penetrating the metal shell of the Geiger counter and participating in the ionization pulses that it counts.


How does the law of universal gravitation explain why gravity between an elephant and earth is greater the gravity between a cat and earth?

The law of gravity says the force experienced is proportional to the product of the two masses and inversely proportional to the square of the distance between them. Effectively on earth the measurement of the force of gravity on a mass is the weight of the mass. As an Elephant has more mass than a Cat, it weighs more than the Cat (because the mass of the Earth is constant).


When common salt is added to ice than what is its melting point?

The freezing point is lowered; the decrease is proportional to the content of salt.

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.

Is counter strike better than condition zero?

Condition Zero is better, but Counter-Strike 1.6 is more popular. Counter-Strike: Source is the best.


Why gm counter is a counter not a detector?

A GM counter is a counter, and not a detector, because it counts ionizing events, rather than quantifying the amount and energy of those events. It has to do with avalanche mode (GM counter) versus linear or proportional mode (ionization detector). The electric potential (higher than that in an ionization detector) between the anode and cathode of the GM counter is such that any ionizing event causes an avalanche of electrons that are counted as one pulse. Since the avalanche occured, the pulse represents only the event, and not its energy. In a linear or proportional detector (counter), however, avalanche does not occur, so the pulse represents the event, and the pulse's energy is proportional to the energy of the event. In effect, the average current through the ionization detector is proportional to the radiation field strength, in units that are meaningful in terms of dose rate. This makes the ionization detector more useful when measuring the relative radiation field, while the higher gain of the GM counter is more useful when simply detecting the presence of radioactivity. The ionization detector is less sensitive than the GM counter, but it is more qualitative.

Why do less people play Counter-Strike Condition Zero than Counter-Strike 1.6?

Counter-Strike 1.6 has been around longer. Condition Zero is better than 1.6, but is generally the same, so people believe it is just a copy of it. I think more people play counter strike 1.6 more than condition zero is because it might have better guns or it is just more popular.

Is counter strike better than half life 2?

No. Counter-Strike is a multiplayer game that used to be a Half-Life mod. It's good and people still play it but Half-Life 2 is better. Although, you're question is kind of dumb because Half-Life 2 is a single player game and Counter-Strike is not. So there's no better or worse.
