Examples of radioactive

• An aliquot was removed to determine the uptake of the radioactive precursor.

• This was used as the starting material for the selective radioactive amplification.

• Production of radioactive nuclides by energetic protons generated from intense laser-plasma interactions.

• By the technique of radioactive dating, it has been shown that the chondrites all crystallized 4.6r 109 years ago.

• Blanks of no radioactive slides were also run.

• In either case the toxic or radioactive waste is trapped in the solid, preventing it from leaching into the local water table.

• The amplified products are visualized on sequencing polyacrylamide gels using radioactive labelling, silver-staining technique, or by using fluorescence-based capillary electrophoresis.

• Mutagenicity tests on bacterial cultures using exceptionally radioactive heavy mineral beach sands : irradiation or chemistry?
