The effects of NMR exposure on living organisms. II. A genetic study of human lymphocytes.

The effects of NMR line-scan imaging procedures and static homogeneous magnetic fields of 0.5 and 1.0 tesla on cells from human blood have been investigated by examining their influence on the frequency of gross lesions, sister chromatid exchanges and on the proportion of amodal cells. Cultured human blood cells have also been submitted to extended NMR imaging exposure during active growth and division. Neither treatment had any significant effect on any of the parameters measured.
