Question

Write a short account (400 words) on the properties of the three main types of ionising radiation.

Answer 1

Ionizing radiation

Radioactive substances give out radiation constantly. There are three sorts of atomic radiation: alpha, beta and gamma. Alpha is the minimum infiltrating, while gamma is the most entering. In any case, every one of the three are ionizing radiation: they can thump electrons out of iotas and shape charged particles.

Radiation can be hurtful, yet it can likewise be valuable - the employments of radiation incorporate to:

recognize smoke

measure the thickness of paper

treat malignancy

disinfect medicinal hardware.

Sorts of radiation

Atomic radiation originates from the core of a particle. Substances that give out radiation are said to be radioactive. All radiation exchanges vitality. There are three kinds of atomic radiation:

alpha

beta

gamma.

Radiation can be consumed by substances in its way. For instance, alpha radiation voyages just a couple of centimeters in air, beta radiation ventures several centimeters in air, while gamma radiation voyages numerous meters. A wide range of radiation turn out to be less extreme the further the separation from the radioactive material, as the particles or beams turn out to be more spread out.

The thicker the substance, the more radiation is retained. The three kinds of radiation enter materials in various ways.

alpha radiation can't go through people, beta is ceased by aluminum, gamma by lead

Penetrative properties of various kinds of radiation

Alpha radiation

Alpha radiation is the slightest entering. It can be halted (or consumed) by a sheet of paper.

Beta radiation

Beta radiation can infiltrate air and paper. It can be ceased by a thin sheet of aluminum.

Gamma radiation

Gamma radiation is the most infiltrating. Indeed, even little levels can enter air, paper or thin metal. More elevated amounts must be ceased by numerous centimeters of lead or numerous meters of cement.
