Male albino mice were given a whole-body roentgen dose of 200 r and were then intraperitoneally injected at various intervals with 4 c Sr/sup 90/. The animals were killed at various times after the injections, and the Sr/sup 90// Y/sup 90/ content of whole blood was estimated. Non-irradiated mice were used as controls. The values of Sr/sup 90/ obtained agree with a theoretical equation expressing the overall state of isotope in blood after an intraperitoneal injection. The constants for the two interacting processes, r for inflow and q for outflow of isotope in the blood, are increased in irradiated animals as compared with controls. This indicates an injury to the transport routes of injected isotope to and from the blood system, induced by a 200 r whole-body dose. This injurious effect of x rays can be demonstrated as early as 5 min after the roentgen treatment. (auth)
