Biological Damage in Mature and Immature Germ Cells of Drosophila Virilis with Ionizing Radiations.
IOLOGICAL damage resulting from radiation treatment has been studied in a B number of biological systems (LEA 1947; HOLLAENDER 1954; BARQ and ALEXANDER 1955). ZIRKLE (1954) discussed the implications of the observed influence of linear energy transfer upon biological damage. More recently BURCH ( 195 7) has discussed several problems of relative biological efficiency with respect to the methods...
متن کاملRADIATION DAMAGE IN THE DEVELOPING GERM CELLS OF Drosophila Virilis.
Since 1945 a great many studies have been made to determine the relation between the amount of damage induced by ultraviolet or ionizing radiations and the chemistry of the cell. One important biological activity which involves both chemical and genetic changes in the cell is the process of maturation with gamete formation. Alexander' has presented new data and reviewed older experiments which ...

متن کاملBiological damage in the mature sperm of Drosophila virilis in oxygen and nitrogen with different dose intensities of gamma rays.
is important to describe radiation damage in terms of primary breakage and I :covery mechanisms in order to determine the possibilities for controlling induced genetic damage. Primary breakage mechanisms would require previous or simultaneous treatments for genetic protection. Recovery mechanisms imply that treatments after radiation injury might be utilized for reducing damage. MULLER (1940) o...
متن کاملRadiation Effects and Damage 1. Ionizing Radiations
The detrimental consequences of radiation are referred to as radiation damage. To understand the effects of radiation, one must first be familiar with the radiations and their interaction mechanisms. Further, the fundamental characteristics of the material(s) being irradiated must also be understood. A brief summary of the characteristics of radiation is first presented below. This is followed ...
