Radioactive Decay & Calculations // HSC Physics

This video analyses the properties of different types of decay: alpha decay, beta minus decay, beta plus decay and gamma decay. At the very end of the video, we also discuss calculations surrounding radioactive decay using the exponential decay formula and equation involving half-life and decay constant.

● analyse the spontaneous decay of unstable nuclei, and the properties of the alpha, beta and gamma radiation emitted (ACSPH028, ACSPH030)

● examine the model of half-life in radioactive decay and make quantitative predictions about the activity or amount of a radioactive sample using the following relationships:

N_t=N_oe^{-\lambda t}
\lambda=\frac{ln2}{t_{1/2}}

where N_t= number of particles at time t, N_0= number of particles present at t=0,\ \lambda= decay constant, t_{1/2}=\ time for half the radioactive amount to decay (ACSPH029)

He is the best tutor. You should watch his Chemistry videos which are even more amazing.
