WHAT IS RADIATION? PART 1 (IONIZING RADIATIONS) EP 1

 Now 

 Alpha particles are heavily ionizing their tracks in a cloud chamber a type of particle detector are thick and short beta rays Centre which consists of energetic electrons are poured in ionizing and leaf thin tracks Gamma Rays right or non ionizing and leave no tracks but give rise to pair the of electron and positron which are ionizing .

IONIZING RADIATIONS 

Effects of ionizing radiation on materials very greatly with the type of radiations the higher the charge of particle the more rapidly it ionizes Alpha particles with the same velocity as a Proton losses energy 4 times as rapidly as the proton because state double the charge of proton and the lower a charged particles velocity the greater is rate of ionization as a charged particle losses energy slowest down and the energy it losses through ionization increase until suddenly the particle no longer has enough energy to ions and atom the particle become neutralized and comes to halt it is said to have come to the end of its range Alpha particles from radium 226 for example have enough energy travel about 20 micrometers in aluminium beta particles electrons on the other hand are far more penetrating this is because of the same energy and electron which has only 0.01% the mass of an Alpha particle has a mus higher velocity and energy losses are inversely proportional to the square of the velocity an electron form the better decay of the carbon 14 Travels about 100 micrometers through aluminium if it had the same energy as the alphabet from the radium 2006 it would travel as a far as 1 cm.
