Pulsed microwave radiation at 24.4 mW/cm² for seven weeks reduced lymphocyte and white blood cell counts in young rats, while 1 mW/cm² for 14 weeks in adult rats showed no significant changes.

Plain English Summary

Summary written for general audiences

Scientists exposed young rats to pulsed microwave radiation at 24.4 mW/cm² for seven weeks and adult rats at 1 mW/cm² for 14 weeks to study effects on blood cells. At the higher power level (24.4 mW/cm²), leucocyte and absolute lymphocyte counts dropped significantly during the second half of exposure. At the lower power level (1 mW/cm²), no significant changes in lymphocyte counts occurred.

Why This Matters

This study compared two experiments carried out in different laboratories: young rats exposed to pulsed microwaves at 24.4 mW/cm² for seven weeks (five days per week, four hours per day) and adult rats exposed at 1 mW/cm² for 14 weeks. The higher exposure was followed by a significant drop in absolute lymphocyte count that persisted after irradiation and disappeared after ten weeks, while the lower exposure produced no significant changes in lymphocyte counts. The two groups also differed in age (immature versus adult), frequency and exposure time.

Quick Questions About This Study

Yes, when rats were exposed to 2736 MHz pulsed microwaves at 24.4 mW/cm² for seven weeks, their white blood cell and lymphocyte counts decreased significantly during the second half of the exposure period.
Lymphocyte counts fell significantly in young rats exposed at 24.4 mW/cm² for seven weeks, while adult rats exposed at 1 mW/cm² for 14 weeks showed no significant changes in lymphocyte counts. The two groups also differed in age (immature versus adult), frequency and exposure time.
Blood was sampled at the first, second, sixth and tenth week after irradiation. The significant drop in absolute lymphocyte count began from the fifth week of irradiation, persisted after the end of irradiation, and disappeared only after ten weeks.
Yes, rats exposed to 24.4 mW/cm² pulsed microwaves showed rectal temperature increases during irradiation, with a mean rise of 0.3°C and a maximum increase of 0.5°C.
The higher-power experiment (24.4 mW/cm²) used 2736.5 MHz with a 395 Hz pulse rate and 2.6 microsecond pulse width, while the lower-power experiment (1 mW/cm²) used 3000 MHz with a 300 Hz pulse rate and 2.5 microsecond pulse width.
