How do I calculate the mass absorption coeficient ao lead given the linear absorption coeficient and the density of lead.Which formula do I use in this case??.

The atomic cross section is often measured in cm-squared per atom, the linear absorption coefficient is in inverse cm per 1/e attenuation, and the mass attenuation coefficient is in grams per cm-squared to 1/e. In Compton scattering, there is another: Energy attenuation coefficient, because primary photons create scattered photons of lower energy and additional penetration. Also, at very high energies, photons create high energy showers comprised mainly of electron, positrons, and photons (plus pions, etc.)

was that an answer to OP's question?

to OP:

you want to go from units 1/cm to cm^2/g, any suggestions?

## 1. What is the definition of mass absorption coefficient?

The mass absorption coefficient, also known as mass attenuation coefficient, is a measure of how much a material absorbs radiation as it passes through. It is a characteristic of the material and is dependent on the type and energy of the radiation.

## 2. How is the mass absorption coefficient measured?

The mass absorption coefficient can be measured using various methods such as X-ray fluorescence, X-ray absorption spectroscopy, and neutron activation analysis. These techniques involve passing radiation through the material and measuring the amount of radiation that is absorbed.

## 3. What factors affect the mass absorption coefficient?

The mass absorption coefficient is affected by the type of material, the energy of the radiation, and the density of the material. It is also dependent on the wavelength of the radiation, with shorter wavelengths having higher absorption coefficients.

## 4. How is the mass absorption coefficient used in scientific research?

The mass absorption coefficient is used in various scientific fields such as material science, environmental science, and medical imaging. It helps researchers understand the behavior of materials when exposed to different types of radiation and can aid in the development of new materials and technologies.

## 5. Can the mass absorption coefficient be used to determine the composition of a material?

Yes, the mass absorption coefficient can be used in conjunction with other techniques to determine the composition of a material. By comparing the measured coefficient to known values for different materials, scientists can identify the elements present in a sample.
