Radiocobalt has been used as a source of gamma rays in a study of the effect of chronic
irradiation on growing plants. The installation and method of operation of sources of …

Plants of Tradescantia paludosa have been exposed to chronic gamma irradiation from a
145 curie source of cobalt-60 for periods up to 5 mo. The gross aspects of vegetative and …

Materials and Methods.-Tradescantia paludosa Anderson and Wood-son was used in all
experiments. Cytological observations were made of chromosomal aberration types four to …

The gamma sources used at Brookhaven for genetical, botanical and ecological studies are
listed and described briefly. They include a 60 c Co 60 hot cell source, a 9 c Co 60 …

Abstract The Brookhaven Gamma Field was established primarily to expose cultivated
plants to chronic gamma irradiation from cobalt-60. However, after about 7 growing seasons …

The cobalt-60 plant and seed irradiation facility at the Atomic Energy Commission
Agricultural Research Laboratory of the University of Tennessee at Oak Ridge is described …

For some time we have been interested in the influence of radiations with differ-ent specific
ionization on the relation of the production of genetic changes to survival and seedling injury …

IT WAS established almost 30 years ago, by Muller and Stadler, that hereditary changes
similar to those occurring naturally could be induced in animals and plants by radiation …

Irradiation of seeds of various crop plants with 3000 r of X rays seemed to stimulate the
growth of lettuce and cabbage, but more critical tests showed no significant effect of the …

The present study reports on some of the morphological, cytological, and physiological
changes induced in green plants by exposure to ionizing radiation. In these experiments …
