When a beta particle penetrates a material, it wil keep corusing until its kinet

Question

When a beta particle penetrates a material, it wil keep corusing until its kinetic energy is totally spent. The depth of penetration depends on the speed of the particle when it enters the material, the density of the material and the nature of radiation. As a general rule, other parameters being equal, a denser will permit a shorter distance of penetration. Using the same radioactive source and placing the different materials listed below from the same distance, arrange the follow materials in descending order of penetration.

a. Concrete

b. Plastic

c. Cardboard

d. Wood

e. Alcohol

f. Lead

Explanation / Answer

Order of materials in descending order of penetration with beta particle is,

a. concrete > e. alcohol < f. lead > b. plastic > d. wood > c. cardboard
