Distinction between the properties of α, β, γ Radiations.

Answer»

Property	α - particle	β - particle	γ - particle
Wavelength	-	-	10^-13m or 10^-3A
Specific charge(q/m)	4.79 x 10⁷Ckg^-1	1.76 x 10¹¹Ckg^-1	-
charge	Positive charge (two time that of proton) = + 3.210^-19 C (or + 2e)	Negative charge = - 1.6 10^-19C (or - e)	No charge
Effect of electric and magnetic fields	Less deflected	More deflected than alpha particles but in direction opposite to those of α - pertivle	Unaffected
lonising power	Maximum	Less than α - particle	Minimum
Penetrating power	Small ( 3-8cm in air)	Large (up to few m in air)	Very large (up to few hundred m)
Biological damage	Causes some damage	Causes more damage	Causes immense damage
