What are the differences between proportional counter and gm counters in radiation monitoring?

The proportional counter is operating in linear mode, so the energy pulse measured by the detector is proportional to the energy of the radioactive particle. Thus, the average current flow in the detector is a function of both the activity (curies) and the energy (kEv) of the source. This detector is better at measuring the dose rate of the source. The Geiger-Muller detector, on the other hand, operates in avalanche mode, so the energy pulse measured by the detector is not proportional to the energy of the radioactive particle. Thus, the average current flow in the detector is a function of only the activity (curies) of the source. This detector is better at measuring the activity of the source, and can be more sensitive to lower energy particles, at the loss of discrimination of what those particles are.

What instrument is used to detect radioactive matter?
Dosimeters detect and measure the cumulative ionizing radiation they see over time. Geiger counters detect the real-time flux of ionizing radiation at a specific location, and scintillators detect individual, real-time ionizing events and usually are constructed in a way to quantify variations in the ionizing energy. Usually, dosimeters are placed on or near an at-risk individual for a length of time to measure their total exposure, while Geiger counters are used by rad-techs to determine how safe an experiment is or if a dangerous event is occurring. Scintillators are used almost exclusively by experimentalists to collect and sort data at high resolution.
Can Lysol wipes be used on granite counters?
Would not recommend it!
What counters the effects of pepper spray?
milk apparently does the trick
Why should oxalic acid not be used on marble tiles and counters?
Oxalic acid cannot be used on marble tiles and counters. This is because it lightens, or even discolors, the color of marble tiles.
Active transport counters the process of diffusion?
No; in a highly selective way it enhances it.
What do you use geiger counters for?
To search for and measure atomic radiation.

What is a Geiger counters used for?
It is used to measure radiation and is commonly used to detect objects that produce nuclear radiation.
What instrument measures radiation in space?
Geiger counters for measuring how much radiation is going on *now*. Dosimeters are carried by the astronauts in order to determine their total radiation dose during the mission.

What type of counters do nuclear physicists develop?
gas tube ionization counters (e.g. geiger counter)crystal scintillation countersetc.There are many other types of detectors that are notcounters (e.g. cloud chamber, bubble chamber, proportional ionization chambers).
What is the collective noun for counters?
Hmm, is that money counters or store counters. Try a staff of money counters or a row of store counters.

How many blue counters must be added so that the ratio of yellow counters to total counters is 1 to 6?
Let the number of Yellow counters you already have is Y Let the number of non-yellow counters you already have is Z Then the current ratio of Yellow counters to the total counters is Y : Y + Z Let the number of Blue counters you add be B After they have been added, the ratio of Yellow counters to the total counters is Y : Y + Z + B This is 1 : 6 Thus Y = 1 and Y + Z + B = 6 → Z + B = 5 Which means that for the Yellow counters you have you will have five times as many counters made up of whatever non-Yellow counters you originally had plus the Blue counters you added. Thus to find out how many Blue counters to add, take the number of Yellow counters, multiply it by 5 and subtract the number of non yellow counters you originally had. examples: You had 6 Yellow counters Add 6 × 5 - 0 = 30 Blue counters Which gives you 6 Yellow and 30 Blue counters → ratio Yellow : total counters = 6 : 30 + 6 = 6 : 36 = 1 : 6 You had 4 Yellow counters and 6 Red counters Add 4 × 5 - 6 = 14 Blue counters Which gives you 4 Yellow counters, 6 Red counters and 14 Blue counters → ratio Yellow : total counters = 4 : 6 + 14 + 4 = 4 : 24 = 1 : 6 You had 4 Yellow Counters, 2 Blue counters and 3 Red counters Add 4 × 5 - (2 + 3) = 15 Blue counters Which gives you 4 Yellow counters, 3 Red counters and 2 + 15 = 17 Blue counters → ratio Yellow : total counters = 4 : 3 + 17 + 4 = 4 : 24 = 1 : 6
If 20 counters are the whole set what fraction of the set is 16 counters?
16 counters is 4/5 of all 20 counters.16/20

25
