Apropos of nothing, US intel looks into improving low-dose radiation detection
[PDF] of the program, IARPA said current methods of collecting biodosimetry data, which looks at the effects of radiation on human or animal tissue, have a number of issues: it can require invasive samples, such as blood; multiple collections are often required; there's a time limit for getting an accurate reading; the markers used to calculate doses are transient; and there's a wide standard deviation of dose calculations for low-dose exposure.
"Today's technology mostly assesses exposure to high doses of radioactive materials by looking at multiple samples that often have limited accuracy for only a few days," said program manager Dr Michael Patterson. Most radiation tests that require blood to be drawn rely on examining chromosomal damage, which IARPA said is unnecessary because recent research"demonstrated that biomarkers associated with ionizing radiation exposure can be detected across numerous biological targets including proteins, peptides, metabolites, and lipids."

Research tests cost-effective approach to early-cancer detection from cell-free DNA in blood samplesEarly detection remains key to successfully treating many cancers, and early detection via cell-free DNA (cfDNA) circulating in the bloodstream—the so-called 'liquid biopsy'—has become a research focal point. But using this method to detect cancer at its early stages has been challenging due to low tumor concentrations in DNA blood fragments and the genetic diversity of cancer.
