Abstract
The present invention provides a method for determining radioactivity in an ion-sensitive field effect transistor array, the method comprising the steps of incubating the array with electron-sensitive silver-halide material and then incubating the array with a developer solution reducing the silver halides that have been exposed to radioactivity to elemental silver and simultaneously measuring pH at each separate reaction chambers, wherein decrease of the pH indicates the presence of radioactivity in a reaction chamber.
