How does activity differ from count rate
WebMar 29, 2024 · The (old) standard unit of activity is Curie (Ci) where 1 C i = 3.7 ⋅ 10 10 decays per second. From the measurement of particle rate as a function of distance you can estimate the total activity of the source S S r. The final relation ship between observed count rate, distance and activity in Ci is as follows: WebMetabolic rate varies with activity level. More active animals have a higher metabolic rate than less active animals. Some animals enter a state of torpor in which their metabolism …

You can show that it is an inverse square by checking that the count rate quarters when the distance doubles ( …
WebFeb 20, 2024 · We define activity R to be the rate of decay expressed in decays per unit time. In equation form, this is (31.5.11) R = Δ N Δ t where Δ N is the number of decays that occur in time Δ t. The SI unit for activity is one decay per second and is given the name becquerel (Bq) in honor of the discoverer of radioactivity. That is, WebThere are general differences in metabolic rate among species, and the environmental conditions and activity level of an individual organism will also affect its metabolic rate. In this article, we’ll take a closer look at the basics of metabolism and see how metabolic rate can vary among species and depending on circumstances.
