What is the definition of the coefficient of linear and mass

Click For Summary

Discussion Overview

The discussion revolves around the definitions and properties of the coefficient of linear and mass attenuation, particularly in the context of radiation. Participants explore how these coefficients relate to different materials and their atomic properties.

Discussion Character

  • Exploratory, Conceptual clarification, Debate/contested

Main Points Raised

  • One participant expresses confusion about the definitions of linear and mass attenuation coefficients and asks if they depend on the material used and the atomic number.
  • Another participant clarifies that the coefficients depend on the material and its density, as well as the atomic number.
  • There is a request for clarification on the specific type of radiation being discussed, indicating that context is crucial for understanding.
  • A participant suggests that providing links to existing definitions could help clarify the confusion, emphasizing the importance of context in the discussion.
  • Questions arise about the differences between linear and mass attenuation coefficients, with a call for more specific information regarding the formulas involved.

Areas of Agreement / Disagreement

Participants generally agree that the coefficients depend on the material properties, but there is no consensus on the specific definitions or differences between linear and mass attenuation coefficients. The discussion remains unresolved regarding the context and specific applications.

Contextual Notes

There is a lack of clarity regarding the specific type of radiation being referred to, which affects the understanding of the coefficients. Participants note that additional context is needed to provide accurate explanations.

hi,
i'm student in a university. I do not understand the definition of these concepts, and I would like to know the properties of these and it depends
questions like
They depend on the material used?
the atomic number?

thanks for answering
capisko,
 
Physics news on Phys.org
Coefficients where, for what?

yes, I'm sorry.
I refer to attenuation coefficients of radiation
 
Which radiation? ...

Independent of the type of radiation: yes, it depends on the material used. On the atomic number but also on the density of the material.

ok thanks! and, which is the difference in coefficient of linear and mass attenuation?
 
Linear in what?
Coefficients in which formula?
There is a lot of context missing here. I cannot even tell if it is nuclear or particle physics (gamma rays interacting with nuclei or free electrons) or atomic/solid state physics (e.g. visible light in matter).

I assume that you've tried web searches on these concepts. I suggest that you give us links to definitions that you've seen already, and try to tell us what you don't understand about them. Then we will have something specific that we can try to clarify. Someone here could try to write up an explanation from scratch, but how would it be more likely that you would understand it than the other web pages out there which we haven't even seen?

Also, as mfb said, context is important.
