A Study on the Shielding Rates of Electromagnetic Fields Using Steel, Aluminum, and Plywood

Research on Electromagnetic Fields (EMF) shielding materials was conducted in order to develop different techniques to reduce the amount of EMF radiation. The researchers compared the effects that a steel box, an aluminum box, and a plywood box had on the amount of EMF radiation inside the said box.

The study was conducted on a small-scale using the three different boxes, a cellphone with an EMF reader, a magnet, and a ruler. The boxes were constructed by hand and made all the same size by modeling them off of a shoe box. The researchers would place the magnet at the 7” mark, and the EMF reader (cellphone) at the 3” mark, the box chosen for that particular trial would be centered over the cellphone so that the reading could be seen through the hole cut out on the front of the box. That reading would be recorded and the process would repeat using the other materials until all the trials were completed.

In addition to finding the some of the best materials to reduce the amount of EMF radiation in an area, this study on alternative shielding methods could produce more data on how much each material reduces the radiation.

The results of the data indicate that steel would be the best at shielding against ambient electromagnetic radiation. Placing steel sheets behind walls with large amounts of electronics can prevent stray radiation from dispersing through walls and affecting the home. Using this method, people can be kept safe from the correlating health effects from the radiation.
