Researchers exposed mice to 2450 MHz microwave radiation (the same frequency used in microwave ovens and WiFi) and found it significantly increased immune cells in their spleens. Even a brief 15-minute exposure triggered measurable immune system changes, with effects peaking after 45 minutes of exposure.

Researchers exposed pregnant rats and their offspring to 100-MHz radiofrequency radiation for 4 hours daily throughout pregnancy and early development. While most health measures remained normal, the study found significant changes in brain acetylcholinesterase activity, an enzyme crucial for nerve function. This suggests that chronic RF exposure during critical development periods may affect brain chemistry even when other health indicators appear unaffected.

Researchers measured how much radiofrequency radiation is absorbed by mice and rats when exposed to three different frequencies: 2450 MHz (microwave oven frequency), 425 MHz, and 100 MHz. They used precise calorimetry techniques to determine specific absorption rates (SAR) - essentially how much energy the animals' bodies absorbed from the radiation. The study compared actual measurements with theoretical predictions across different animal sizes and orientations.

Researchers exposed female mice to 425 MHz radio frequency radiation for one hour daily over five days, testing both continuous and pulsed wave signals at various power levels. The study found no effects on the mice's primary immune response to sheep red blood cells, as measured by antibody-producing cell counts.

Researchers exposed rats to 2800 MHz microwave radiation for 90 minutes before testing their ability to learn new sequences of behaviors. At higher power levels (5-10 mW/cm²), the microwaves disrupted the rats' learning ability, causing more errors and slower completion of tasks. This demonstrates that microwave radiation can impair cognitive function even at relatively low exposure levels.

Researchers exposed pregnant rats to 2450 MHz microwave radiation (the same frequency used in microwave ovens and some WiFi) to study birth defects. The study found that specific abnormalities only occurred at radiation levels high enough to kill the mother rats, while lower levels still caused reduced fetal body weight and brain mass.

This technical report examined the effects of 2.45 GHz microwave radiation exposure on pregnant mice, focusing on potential developmental impacts during pregnancy. The research investigated whether microwave radiation at this frequency could cause birth defects or other reproductive harm. This frequency is commonly used in microwave ovens and some wireless devices, making the findings relevant to human exposure concerns.

Researchers exposed rats to 2.45 GHz microwave radiation (the same frequency used in microwave ovens and WiFi) at various power levels for 4 hours and measured stress hormone levels. They found a surprising dual effect: low-level exposures actually suppressed the normal rise in corticosterone (stress hormone), while high-level exposures dramatically increased it. This suggests microwave radiation can disrupt the body's natural stress response system in complex ways.

Researchers exposed rats to 2450-MHz microwave radiation for 45 minutes at low power levels (0.6 W/kg) and measured effects on brain neurotransmitter systems. They found that microwave exposure disrupted choline uptake in multiple brain regions, with different effects depending on whether the radiation was continuous or pulsed.

Researchers exposed rats to 2450 MHz microwave radiation (the same frequency used in microwave ovens and some WiFi) for 30 minutes at different power levels. They found that even moderate exposure levels caused temperature changes, slowed heart rate, and reduced metabolism for hours after exposure ended. The effects were dose-dependent, meaning higher power levels caused more severe and longer-lasting physiological disruptions.
Stern
This research by Stern examined how microwave radiation at 2450 MHz affects temperature regulation behavior in laboratory rats. The study found that microwave exposure altered how rats naturally respond to temperature changes, suggesting these electromagnetic fields can disrupt biological processes that control body temperature. This matters because it demonstrates microwaves can affect fundamental biological functions beyond just heating tissue.

This French research study examined internal organ damage in mice and rats exposed to ultra-short wave radiofrequency radiation. The study focused on visceral lesions (tissue damage to internal organs) and potential effects on reproductive systems. This early research contributed to understanding how RF radiation might cause physical damage to living tissue.
