MicroRNAs track radiation doses

Blood levels of genetic material could help identify people at risk after exposure

microRNA and radiation

MOLECULAR GEIGER COUNTER  The abundance of small pieces of genetic material called microRNAs falls or rises in the blood of mice after radiation exposure. A lethal dose of 8 grays of radiation (red dots) produces a different pattern than a serious but survivable dose of 6.5 grays (black triangles).
