Description
$^{90}$Sr is among the most hazardous fission products with a high production yield in the nuclear fuel cycle and is of great environmental interest due to its radiotoxicity as well as its potential as a tracer. Accelerator Mass Spectrometry (AMS) is the technique of choice for the detection of minute environmental levels of long-lived radionuclides, but the background from the abundant stable atomic isobar $^{90}$Zr has so far prevented its use for $^{90}$Sr. The novel Ion Laser InterAction Mass Spectrometry (ILIAMS) setup at the Vienna Environmental Research Accelerator (VERA) overcomes this problem by neutralizing the isobar via non-resonant laser photodetachment.
