9. Types Of Radiations Used In CT-
Scans:-
1.TheX-raysareaformofionizingradiation,which
meansthattheyhaveenoughenergytoremove
electronsfromatomandmoleculesinthebody.
2.AlthoughtheamountofradiationusedinaCTscansis
relativelyLow,thereissmallriskofradiationexposure,
particularlyforrepeatedscans.
3.Tominimizethisrisk,radiologictechnologistsand
