This 1966 study exposed dogs to 2.8 GHz microwave radiation (100 mW/cm²) combined with X-ray radiation to test how microwaves affect the body's response to ionizing radiation. Dogs that received microwave exposure showed significantly higher death rates, particularly when microwaves and X-rays were given simultaneously. The deaths were blood-related, suggesting microwaves compromised the animals' ability to recover from radiation damage.

This 1966 study examined how dogs' white blood cells responded when exposed to both microwave radar radiation and X-rays simultaneously, compared to X-ray exposure alone. Researchers found that dogs exposed to both types of radiation showed different white blood cell changes than those exposed only to X-rays. This matters because radar workers face potential dual exposure to both microwave and ionizing radiation.
