At Brockhaven Nat Lonal and the amount of visible chromosomal damage. Laboratcry, it was founa that the mutation frequency was closely correlated with the chromosomal danage but not correlated with growth inhib Ltion,. This means that with thermal neutrons many more mutations will 1De Dp roduced for a given degree of injury than for * rays, and thus thermal n PULLTONS give great promise as a tool for genetic study.
