Use Cases

RadWatch gamma analysis:

• Import SPE file
• Apply known energy calibration if needed (should already be in SPE)
• Verify energy calibration and adjust
• (Subtract background?)
• Look for peaks at given energies
• Get net area or MDA
• Apply known efficiency calibration
• Get Bq for each isotope of interest
• Use sample metadata to get Bq/kg for sample

##Neutron Activation Analysis:

• Import SPE file
• Apply known energy calibration
• Perform peak search
• Peak identification (possibly computer-assisted using isotope data from web)
• Peak fitting, net area
• Apply known efficiency calibration (or use a reference sample...)
• Get Bq for each isotope
• Use irradiation and measurement metadata to compute elemental quantities

##Energy calibration:

• Repeat as needed:
• Import SPE file
• Perform peak search
• Peak identification (by user)
• Create energy calibration
• Optionally: Measure FWHM vs. energy
• Optionally: Save energy calibration into SPE file

##Efficiency calibration:

• Repeat as needed:
• Import SPE file
• Apply known energy calibration
• Look for peaks at given energies
• Input source activity with isotope branching ratios (down the line, this could be connected with the isotope data from web, and half-life calculation using reference activity & date)
• Create efficiency calibration
