Q: My daughter wants to do a science fair experiment on the efficaciousness of cell phone shielding devices versus putting your cell phone in your jean pocket or purse. She is concerned about the RF radiation risk to the human body. I looked on-line for a RF detection meter. There are a plethora of devices with a great price range from $34 to thousands of dollars. Please help me. Do these work? Do you have a criteria for these? Thank you!
