Cyclotron Produced 44gSc from Natural Calcium

Here, the 99.99% curve implies an reactivity of 51 GBq/μmol. Overall, the reactivity was 54 ± 14 GBq/μmol (n=4) corrected to EOB. Fig. 3 also shows a representative titration when 99% pure calcium was used for production. An almost ten-fold increase in reactivity was observed when using 99.99% calcium over the less pure metal.

Calcium - Element information, properties and uses

Calcium is what is known as an essential element, meaning that it is an element which is absolutely necessary for life processes. Which is what the old milk TV adverts were trying to tell us after all. Calcium is used to produce the minerals contained in bones, shells and teeth through a process called biomineralisation.
