Thank you, but you are not answering my question. My A level book says that lambda is the probability of decay per second. And the equation provided to A level students is here. It says that activity in Bq is equal to lambda x N (number of unstable nuclei) This makes sense for small values of...

I am thinking about lambda, the nuclear decay constant and what it actually means. I have built spreadsheet models looking at decay using lambda to determine the decay for each time period and then comparing the number left to that determined by using e ˆ- lamda x time. These are my...
