Why is beta radiation used to measure thickness?

Answer 1

The essence of the process is that gamma rays are passed through the object and measured, or they are passed through and backscattering is measured. The thickness can be calculated from the reduction in radiation. The nature of the object needs to be known, of course. The physical law involved is called Beer's Law, or the Beer-Lambert Law, or sometimes simply the exponential absorption law.

Answer 2

Beta radiation is used to measure thickness because it has low penetration power, allowing it to measure thin materials without passing through them. This makes it ideal for applications where precise measurement of thin materials is required, such as in the manufacturing industry. Additionally, beta radiation can easily be detected and measured, providing fast and accurate results.

Answer 3

Because alpha has a weak penetration power and gamma has a powerful penetration power

Answer 4

Because its attenuation is proportional to thickness being penetrated
