Scintillation counting system using scintillator capsules

A scintillator capsule for producing scintillations in response to radioactive substances in a sample, said scintillator capsule to be located with said sample and comprising:

• a liquid scintillator core being hydrophobic and having a fluorescent substance for converting radiation energy from said sample into light energy and at least one solvent for dissolving said fluorescent substance;
• and
• a plastic wall surrounding said core, said wall having a diameter less than 3000 microns and being permeable to said light energy and to said radiation energy from said sample, said core being located inside said wall and said sample being located outside of said wall.

A scintillation counting system for performing scintillation counting on a sample using scintillator capsules located with said sample to produce scintillations in response to radioactive substances in said sample, each of said scintillator capsules comprising:

• a liquid scintillator core having a fluorescent substance for converting radiation energy from said sample into light energy;
• and
• a wall surrounding said core, said wall having a diameter less than 3000 microns and being permeable to said light energy and to said radiation energy from said sample, said core being located inside said wall and said sample being located outside of said wall.
