Question

Attenuation of a radiation beam's intensity as it passes through an absorber is governed by

1. Time
2. The specific mediums density
3. The energy of the radiation
4. The thickness of the absorber traversed

Answer 1

Attenuation of a radiation beam's intensity as it passes through an absorber is influenced by time, the specific medium's density, the energy of the radiation, and the thickness of the absorber traversed.

Factors such as the type of radiation, energy of the particles or photons, number of particles or photons that strike a given area per unit time, and the chemical nature of the substance exposed to the radiation also affect the attenuation process.

Step-by-step explanation:

Attenuation of a radiation beam's intensity as it passes through an absorber is governed by several factors. These include:

1. Time
2. The specific medium's density
3. The energy of the radiation
4. The thickness of the absorber traversed
   

The type of radiation, energy of the particles or photons, the number of particles or photons that strike a given area per unit time, and the chemical nature of the substance exposed to the radiation all play a role in the attenuation process.

For example, as the x-ray energy increases, the Compton effect becomes more important in the attenuation of the x-rays. The probability for attenuation depends on the number of electrons present, the material's density, and the thickness of the material.
