Radiochemical Methods Flashcards
Based on the measurements of the radioactivity or radiation produced in samples when they are irradiated with neutrons or charged particles
Activation method
Used as internal standard for quantitative work
Isotope dilution
For analytes that are mot naturally radioactive, ____ can be used to induce radioactivity
Neutron activation
Which of the ff are rdiochemical methods
A. Activation analysis
B. Tracer analysis
C. ultra trace analysis
D. Natural radioactivity.
ABD
Done to reduce the health hazard associated with higher levels of radioactivity
Cooling
Non-destructive radiochemical methods
Neutron Activation Analysis (NAA)
Isotopically labeled species
Tracer
Requires preparation of a quantity of the analyte in a radioactive form
Isotope dilution
Radiochemical method wherein the radioactivity is induced on ine or more elements of the sample by irradiation with suitable radiation or particles. the resulting radioactive emissions are them measured
Activation analysis
Radiochemical method wherein the radioactivity is physically introduced to the sample by adding a measured amount of radioactive species
Tracer analysis
Three sources of neutrons employed in neutron activation method
Reactors
Radionuclide
Accelerators
In Neutron Activation Analysis, the samples may be solids, liquids or gases.
True. Most common are solids and liquids
Isotope dilution
