alpha particles||Linear Energy transfer||Braggs peak||Mass stopping power||energy loss formula

Energy transfer mechanism of alpha particles is discussed. Range energy relationship is used to calculate the range of alpha particles in air, in aluminum and in human tissue. Examples 5.8, 5.9, and 5.10 of chapter 5 Introduction to health Physics by Herman Cember and Thomas E Johnson are solved. The graph between specific Ionization and the range of alpha rays is discussed. The Bragg's peak is explained.
