Interpretation:
The type of window that can be employed for an alpha source containing metal container is to be explained.
Concept introduction:
In a nuclear reaction, unstable nuclide disintegrates into stable nuclide with emission of various radiations spontaneously. It is called radioactivity of nucleus. Emission of rays like alpha, beta and gamma rays occur in the process which changes the identity of nucleus.
During a nuclear change, an element undergoes change in its
Answer to Problem 92A
Alpha radiations are heavy in mass so cannot penetrate into layer of dead layer of human skin and can be blocked easily by a thin sheet of metal foil. Therefore, the type of window that can be employed for an alpha source containing metal container depends on intensity of alpha radiation or quantity of radiation.
Explanation of Solution
An alpha particle is one that has 2 unit positive charges and is equivalent to helium atom
So due to heavy mass, it cannot penetrate into layer of dead layer of human skin and can be blocked easily by a thin sheet of metal foil. Therefore, the type of window that can be employed for an alpha source containing metal container depends on intensity of alpha radiation or quantity of radiation.
