What Is IPS in Geiger Counter Measurements?

Click For Summary

Discussion Overview

The discussion revolves around the meaning and implications of the unit IPS (Impulse per Second) in the context of Geiger counter measurements for detecting gamma rays. Participants explore its relationship to other units such as counts per second and Sieverts per hour, and seek clarification on conversion methods and definitions.

Discussion Character

  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant, Rajini, inquires about the definition of IPS and whether it corresponds to disintegrations per second.
  • Another participant suggests that "Intensity per second" is not a meaningful term and proposes that IPS likely refers to detected counts per second.
  • Rajini asserts that IPS stands for Impulse per Second, as indicated in the manual, and requests a conversion relationship to Sieverts per hour.
  • A participant notes that the readings on Geiger counters can vary by make and model, indicating that there is no universal conversion from counts per minute to exposure rates due to differences in efficiency and geometry.
  • Another participant confirms that Impulse per second is equivalent to counts per second and reiterates that converting counts per second to Sieverts requires manufacturer calibration.
  • Rajini acknowledges that calibration by the manufacturer is necessary for conversion from IPS to Sieverts per hour.

Areas of Agreement / Disagreement

Participants express differing views on the definition of IPS, with some supporting the idea that it refers to counts per second while others maintain it is Impulse per Second. The discussion remains unresolved regarding the exact nature of IPS and the feasibility of conversion to Sieverts per hour without manufacturer-specific calibration.

Contextual Notes

There are limitations regarding the assumptions made about the definitions of IPS and the conversion processes, as well as the dependence on specific Geiger counter models for accurate readings and conversions.

Hallo friends,
I have some Geiger counter for detecting Gamma rays...By this meter one can measure in IPS (Intensity per second) or Siever/hour...Now i need to know What is this new unit IPS...Does anyone heard about it...or does it directly corresponds to the disintegrations per second (i.e.,decay per second)...Its better for me to know some formulas regarding this IPS..
thanks for your reply

Physics news on Phys.org
"Intensity per second" doesn't make sense - I suspect it means detected counts per second.
 
No its Impulse per Second...i am sure about...its also given in the manual..Anyways..if u think its intensity per second..then can u give some relation about it...for e.g., converting IPS into Siever per hour...this will be helpful for me..
thanks again
Rajini
 
It depends what the meter face says. Most meter faces read in cpm (counts per minute) or some unit of exposure/dose per hour, but then, it all depends on your make and model number. There is no direct conversion from cpm to exposure rates that is uniform across all makes and models of survey meters. This is due to differences in efficiency/geomtery of the different makes and models.
 
actually my radioactive material with a initial activity of 1850 MBq (50 mCi)..so when we expose the counter directly over the radioactive material...what it will show in IPS or in sieverts per hr...or do u think this is mad question...
 
Impulse per second is the same as counts/sec.
Intensity / second doesn't make sense because intensity is already per second.
As daveb said you can't easily convert from cps to Sieverts unless the maker supplies a calibration.
 
Oh...thanks for the tip..so the manufacturer adopt some calibration conversion...for IPS into S/hr..so there is no relation for this conversion...
