the ionizing radiations. The hope is entertained, therefore, that a knowledge of the influence of modifying factors on the effectiveness of chemical agents rep- resentative of several groups of radiomimetic compounds would provide a clue as to their mode of action within the cell.

because the oxidation of nitrogen under the action of ionizing radiation is one of the possible effective methods of utilizing atomic energy for bringing about chemical synthesis. In addition, the availability of the system and its initial simplicity have caused it to be the subject of many studies of the relations between primary activa-

The effect of nitrogen mustard and of ether on the mitotic activity in rat s corneal and intestinal epithelium is being studied at the present time. Cytology (A. M. Brues, A. N. Stroud, and H. L.

Radiation Chemistry of the Fixation of Nitrogen

fixation of nitrogen is the binding of the nitrogen gas of the air with the oxygen gas of the air. The final product is nitrogen dioxide, NO2 or the dimer N204. Unfortunately, the intermediate reaction leading to NO2 formation-namely, N2 +02 -2NO (1) is endothermic by 42 kilocalories and does not proceed under normal condi-tions.

CYTOGENETICS AND MUTATION BREEDING OF SOME OIL YIELDING

most mutation breeders prefer ionizing radiations due to easily applicability and high mutation frequency. Sometimes thermal and fast neutrons can be used. The dose to apply depends on the radiosensitivity of the species in general and that of plant part and the stage of development in particular. Plant parts

Chemical reactions (effects) induced by ionizing radiation are the field of radiation chemistry, which must be separated from radiochemistry (the study of radioactive nuclei). Radiation Chemistry and Photochemistry are closely related: Photochemistry: chemical reactions induced by light (energy in the range 1 10eV or

Nature of radiations Rutherford subjected the radioactive radiations under the influence of electric and magnetic fields. A small amount of radioactive substance is taken on a lead block. The radioactive radiations which are emitted are then passed through the slit. After this, these are subjected to the action of electric and magnetic fields.
