Use the power of stainless steel to block microwave radiation!This unique apron is constructed using our special cotton based StaticotTM shielding fabric which is a highly effective E-field and RF shield, providing up to 40 dB to 10 GHz according to test results. 20 Ohm per square on the surface, so it is also great for static discharge and easy to make ground connections. Soft feel and gentle to the skin. Completely machine washable (no bleach) and dryable (cool) without losing shielding performance. Generously cut for comfort and great "neck to hip" protection for pregnant women, computer and microwave oven users, TV or radio station workers, research and hospital workers, or anywhere people are exposed to RF radiation.
