The disks are available in two sizes: 1 1/2" or 1" diameter.  The smaller disk was designed specifically for children and small pets.  The larger disk is commonly worn around the neck on a chain or cord.  Many computer operators around the world wear a large disk to help protect them from the growing concern over electromagnetic radiation from computer monitors.
What About My Pet?	See Electromagnetic Radiation for further details about EMR.
	Of particular concern to mobile/cellular phone users is the affect of radiation on brain tissues. Even particularly insensitive individuals have reported "hot spots" or headaches when mobile phones are used for more than a couple of minutes, and news media reports indicate the scientific jury is still out about the degree of harm that could be involved.  However, users of mobiles report a marked reduction of these unpleasant effects when a Disk or Angel is attached to the back or side of the phone with an adhesive or with tape. (As close to the antenna as possible.)
	Positive Energy Disks attached to your pet's collar will let him/her enjoy the same positive energy you enjoy with your Positive Energy Plates.  Or … create a necklace using a chain or thin silk rope, attach it to your key-chain, put one on the inside of each shoe, attach it to your child's clothing (remembering to protect them from swallowing small objects), or drop one in your shirt pocket.
