5. • Activity
• • It is a dosimetric quantity
• – measured by number of disintegrations N per
time unit t
• – SI unit of activity is 1 Bq (Becquerel)
• – 1 Bq is activity of radioactive substance, where
one
• disintegration occurs per one second 1Bq = 1/1s =
[s-1]
• – Non SI unit = 1 Curie = 3.7*1010 Bq = 37 GBq
