PHYSICS 2011 Unit 1 VCE CHEAT SHEET

FORMULA’S:

To Find Absorbed Does:AbsorbedDose= Equivalent Dose

Quality FactorTo Find Does Equivalent:

Equivalent Dose=Quality Factor× Absorbed Dose

To Solve Quality Factor:Quality Factor= Equivalent Dose

Absorbed Dose

To find Half-life or Calculate (mg) needed:

n=TimeTakenHalf −Life

And Start=End×22 (¿ ) End=Start ÷2n

Converting (eV) to (J):1eV=1.6×10−19 Joules

---------------------------------------------------------------------------------------------------------

UNITS: CHANGING OF UNITS:

To find neutrons: Nucleons - ProtonsQUALITY FACTORS: To find nucleons: Neutrons + Protons

If given ‘Au-197’: Neutrons - Atomic No. Alpha (20)Beta (1) DETERMINING THE DECAY:Gamma (1) Beta Decay: > X−1

0

Alpha Decay: > X24
