EFFECT OF X-RAY IRRADIATION OF VERY SMALL DOSES ON THE BLOOD PICTURE
The changes in the blood pictures of those engaged in photo- roentgenography and thus exposed to scattered x rays totalling 30 to 200 mr were examined after the end of their work at times of 15 min, 30 min, 24 hr, 48 hr and a week. Most of the cases received irradiations of 40 to 70 mr. After the irradiation, a transient increase in the total leukocyte count due to increase of neutrophil cells within 24 hr, or a transient increase in lymphocytes after 24 hr was observed in most cases. In cases where the neutrophil cell count remained nearly unchanged or decreased, the lymphocyte count was found increased, but in cases where the lymphocyte count remained unchanged or decreased, the neutrophil cell count was found increased. When the same individual was exposed to irradiation of the same quantity on different occasions, the resultant changes in his blood picture or the time of the appearance of the changes were varied. The grade of the reactions in blood pictures was not proportional to the quantity of the total irradiation. In the cases exposed to scattered x rays for the first time, the changes in the total leukocyte count and neutrophil cell count were larger than the blood changes of the professional radiological workers exposed to scattered x rays for a long time.
