How can I shield my Smart meter?

A Smart meter is a radiofrequency (RF) emitting device that the utility company has installed on your gas or electric meter. The RF signal emitted transmits information back to the utility company about your gas or electric usage. The signal is intermittent, but operates 24/7. Usually, the utility company will not permit you to completely block this transmission. However, you can shield your body and your living space to minimize the amount of RF exposure you receive.

There are two main categories of shielding materials that can be used:

An RF reflector will cause the majority of the signal to bounce off, somewhat like a mirror reflects light. It can have very high shielding performance, and in general should be grounded for peak efficiency. It will usually offer better shielding (less RF transmission) than an absorbing material. An RF absorber will absorb the much of the signal, and minimize reflection. The energy absorbed is released as a tiny, almost unmeasurable amount of heat. Grounding is usually not needed. In both cases, SOME amount of RF does get through the shield, as no shield is 100% effective. You can use double or triple layers of shielding to improve performance.

So where should I put the shield? And how much area do I need to cover?

So which one is right for your situation? In a hypothetical world where your Smart meter is the only source of RF radiation, either absorbers or reflectors would work well. However, in the real world, there will be multiple sources of RF radiation. Some of them might be right inside your own home. Some might be coming from other directions. In such a situation, if you use a reflecting material, it will reflect on BOTH sides, and you could end up increasing the amount of RF in your living space. On the other hand, if you use an absorber, it will absorb on BOTH on both sides, so you cannot increase your exposure. If, you use both materials, a reflector on the side closest to the RF source, and an absorber on the side closest to the living space, you get the best of both materials... and the absolute lowest RF transmission. Any small amount of Smart meter signal penetrating the reflector will be absorbed by the absorber. Any signal coming from the opposite direction will have to pass through the absorber, then reflect off the reflector, and finally pass through the absorber again before it re-enters the living space. This would be a very small amount indeed.

Which shielding materials do you recommend? Reflectors for a wall: Fabrics such as RipStop Silver and Ni/Cu Ripstop are good choices. Use two layers and be sure to ground them. Paints such as Y-Shield and CuPro-Cote are good choices. Drapes and curtains for windows: VeilShield and High Performance Silver Mesh allow good light penetration. Absorbers for a wall: Laminated MW Absorber is a convenient, 48 inch wide film that is very low cost and easy to install. You can cover over your shielding materials with almost any decorative medium that you like. The shielding should be protected from abrasion, excessive flexing, and moisture. Shielding Garments and Bedding: Find a variety of shielding hats, shirts, gloves and more to wear on your body. These unique Swiss fabrics can be used to make washable shielded bedding and clothing. Use a Faraday canopy to make shielded enclosure. A portable Shielded Sleeping Bag is also available.

Which meters do you recommend? We recommend the High Frequency Meter or We recommend the Acoustimeter These 2 meters have fast enough response to measure the short radiation bursts.
