Abstract
A solid phase scintillation counting method is provided wherein a scintillating material is added to an inert carrier and a radioactive substance is caused to contact the carrier either before or after the scintillating material has been applied. The treated carrier is then counted in the solid state in a liquid scintillation counter without the necessity of dissolving the radioactive substance in a liquid solution containing a scintillator. The invention provides a highly efficient and very convenient method for counting low energy radioactive isotopes such as .sup.14 C and .sup.3 H.
