I think you meant to say "one year is defined as 365.25 days, not 365 days" (in which case you might want to make it 365.2425 days, or 365.2422).

May I suggest adding more info about radioactive decay?
This wikipedia link should be sufficient: https://en.wikipedia.org/wiki/Radioactive_decay#Half-life
