If for some radiobiological effect the form of the doseresponse is different for two radiations, the value of the RBE will vary with the dose, and a single value at just one level of effect will by itself alone convey little information. If, however, a linear term were present in the doseresponse, it would predominate at low doses or long exposure times and then the RBE of two radiations would approach a constant limit. This situation was investigated for chromosome aberrations in Tradescantia microspores produced by shont and long exposures to fast neutrons and gamma-rays. The data indicate that at low doses or long exposure times the RBE of the fast neutrons is high and must approach values of the order of 100.
