ตัวอย่าง 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?

• Such preparations are metabolically active as shown by then* ability to metabolize radioactive glucose.

• In recent years, regulatory problems associated with the use of radioactive materials have limited their use in field studies.

• In radioactive beam generation experiments, resolution of the isotopes and transmission of the secondary beam through the fragment separator are very important problems.

• It is expected that the latter can regulate the crossfield plasma particle transport in tokamak discharges which are contaminated by radioactive dust.

• This is the core of a new technology developed to treat buried low-level radioactive or toxic waste.

• Erosion of the granites yields specific minerals including quartz, radioactive (uranium-, thorium-bearing) phases and phosphates, which could play a role in early evolution.

• Examples of hazardous systems include those used in the production, storage, and transportation of environmentally harmful materials, such as oil or radioactive waste.
