Suppose the range for 5.0 MeVa ray is known to be 2.0 mm in a certain material. Does this mean that every 5.0 MeVa a ray that strikes this material travels 2.0 mm, or does the range have an average value with some statistical fluctuations in the distances traveled? Explain.

Expert Solution & Answer
To determine
Whether it means that every 5.0 MeVαray that strikes this material travels 2.0mm , or the range have an average value with some statistical fluctuations in the distances traveled, suppose the range for 5.0 MeVα ray is known to be 2.0mm in a certain material
Answer to Problem 1CQ
Every 5.0 MeVa a ray that strikes this material won't travel 2.0 mm.
Explanation of Solution
Concept Used:
Nuclear radioactivity.
The distance travel by the radiation through a material is defined as the range of the radiation. The range of radiation depends upon some of the factors which includes the energy of the radiation, the material through which it travels and the type of the radiation whether alpha, beta or gamma ray. By defining these factors or by knowing these factors we can know the range of the radiation. Here it is given that range of radiation is 2 mm for a certain material, But the charged particles in the material interacts with rays and because of that ray will show some random fluctuations, so every 5.0 MeVαray won't travel 2.0mm on the same material. In the α decay the energy released in it is about MeV range. It is about 106 for a typical chemical reaction. Most of the energy is converted in kinetic energy of the α particle which moves at high speed
Conclusion:
Thus, every 5.0 MeVa a ray that strikes this material won't travel 2.0 mm.

8. An x-ray beam is composed of equal intensities of 30 pm x-rays and 50 pm x- rays. The xray beam is now directed upon a material whose linear absorption coefficient for 30 pm xrays and 50-pm x-rays are 0.30 mm-1 and 0.72 mm-1 respectively. How thick is thematerial if the exiting x-ray beam is composed of twice as many 30 pm x-rays as 50-pm xrays?
