Ionization chamber and GM tube

AI Thread Summary
Ionization chambers and GM tubes differ primarily in their structure and operational pressure, which affects their functions. GM tubes operate at low pressure and require higher voltage to facilitate electron avalanche, while ionization chambers function at normal gas pressure and are connected to a galvanometer. Although applying higher voltage to an ionization chamber could theoretically allow it to function like a GM tube, practical differences in design and application remain significant. The ionization chamber is typically used for measuring lower radiation levels, while the GM tube is suited for detecting higher levels of radiation. Understanding these distinctions is crucial for their appropriate application in radiation detection.

Homework Statement



What are the difference between ionization chamber and GM tube in structure which make them have different functions?


The Attempt at a Solution



Higher voltage is applied to GM tube so that electron avalanche can occur.
Then I wonder that
if higher voltage is applied to ionization chamber, it can function as a GM tube.
 
Physics news on Phys.org
The difference is...
ionization chamber is connected to galvanometer and operate at normal gas pressure
while GM tube is connected to a counter and operate at low pressure

Is it?
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
