The resolving time in a GM counter refers to the time it takes for the counter to provide a measurable output signal in response to an incident radiation event. This time is important for determining the instrument's ability to accurately detect and count radiation events in real-time. A shorter resolving time generally allows for faster and more precise measurements of radiation flux.
Dead time refers to the time during which the GM counter is unable to detect another radiation event due to the voltage applied. Recovery time is the time needed for the counter to reset and be ready to detect another radiation event after being triggered. Dead time affects the count rate accuracy, while recovery time influences the overall efficiency of the GM counter.
The dead time formula in GM counters originates from the time it takes for the counter to recover after a detection event, during which it cannot detect additional events. The formula is used to calculate the rate at which the counter underestimates the true count of events due to this recovery time. It helps in correcting the count rate to account for dead time effects.
The trigger on a Geiger counter is typically called the "dead time." It is the period during which the counter is unable to record additional radiation events because it is processing a previous one.
Transmission electron microscopes (TEMs) typically have the best resolving power, capable of resolving objects down to the atomic level. This is due to their use of a beam of electrons, which has a much shorter wavelength than visible light used in other microscopes.
The resolving power of a microscope determines the sharpness of its images. Resolving power refers to the microscope's ability to distinguish between two points that are close together. A microscope with higher resolving power will produce clearer and sharper images.

Some limitations of GM counters include limited efficiency at high count rates, inability to discriminate between different types of radiation, and the need for periodic calibration and maintenance. Additionally, GM counters are typically bulky and require a high voltage power supply for operation.
Secondary emmission
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.
A GM counter has an anode that is held at a positive high voltage potential. This is so it can attract electrons released by ionization events in the shell. When an event occurs, electrons are transferred to the anode, temporarily reducing its voltage, hence the negative going pulse.
Some Geiger counters can be used to detect gamma radiation. A better device for detecting gamma raysis a sodium iodide scintillation counter.
A Geiger-Müller (GM) counter is used to detect ionizing radiation, specifically from various nuclear decay processes like beta decay, gamma decay, and sometimes alpha decay.
