In a nasal swab bioassay, which category can be detected?

Explanation:
The nasal swab bioassay is most effective for detecting gamma-emitting radionuclides because gamma rays can escape from the nasal tissues and swab material and be measured with a gamma detector. Alpha and beta emitters have very short ranges in air and tissue, so their signals are largely absorbed before they can be detected reliably from a swab. Neutron emitters require specialized detectors and aren’t detected by standard gamma-counting approaches used with nasal swabs. So, gamma emitters are the category that can be detected in this type of assay.
