Radioactivity calculator

(The original version can be found here.)

NOTE: The calculations are performed by JavaScript, which is built in to current versions of Netscape and Internet Explorer. Your browser does NOT support JavaScript -- either because it is too old, or because JavaScript (or VBscript) is disabled in an Options or Preferences dialog. Although you can see the calculators below, they won't work.

Use these calculators to perform routine radioactivity calculations for biochemical and pharmacological experiments (detailed explanations).

A. Isotope decay

B. Conc. of stock

C. Dilution of stock

D. Specific activity (cpm/fmol)

E. Cpm to fmol/mg

F. Cpm to sites/cell

G. Cpm to nM
