Radioactivity (10 of 16) Decay Activity, Example Problems
Goes over four different worked examples for calculating activity and half-life from radioactive decay. Activity is defined as the number of decays per second. It is abbreviated with the symbol A and has the metric unit the Becquerel (Bq). One Becquerel is equal to one decay per second.

Glad it helped!
what will be the activity of elemnet of a=625mci h.l = 8 days after 20 days becouse i get different result from online calculator of activity
what is the activity of cobalt 60 after 8 years,if the present activity is 100 curie
Thank you so much! This helped greatly.

Please make videos about center of mass of point particles and for infinitesimal ...
Bruh ! U have to come here to Japan, there's no teacher who put this type of questions in the exam, our physic is just math

What if at 7:00 you have that the half-life is 9.7 hr and it's asking you to find what amount remains in Bq after 12 hrs? Bc I was trying to follow you and did 12 hr/9.7 hr and got 1.23711 half-lives, which means that the Activity (in Bq) will be some # between the first and second half-life [T1/2 (1) and T1/2 (2)], how do you find that exact # (the Activity)?
