DOES THERE EXIST MUTATIONAL ADAPTATION TO CHRONIC IRRADIATION?
The results do not confirm the assumption that under the increased radiationbackground mutational adaptations occur due to incorporation in the population
of mutational isoalleles with lower mutability.

SOME RESULTS AND PREVIEWS OF RESEARCH IN SWEDEN. RELEVANT TO
HUMAN RADIATION GENETICS
Summarizes the present state of knowledge and recommends: (1) Large scale
international investigation of genetic consequences in females who have been
controlled by means of X-rays due to congenital dislocation of the hip. (2) The
study of genetic effects of radiation on humancell cultures.
