Ever wonder if you are getting too much sun exposure?  Skin Test Technologies UV Detector Card (Enviroscan.net) measures the intensity of the UV rays in the enrivonment you are in.  After 10 seconds, the card changes color to determine the strength of the UV (both UVA and UVB) emitted.  The card becomes particularly useful for those with skin cancer or who have recovered from skin cancer, who are wondering if it is safe to go outside.  Although the FDA states that it is best to avoid the sun between the hours of 10 AM and 4 PM, if you want a more accurate determinant, the UV Detector Card is a great way to go.

The UV Detector Card works pretty well out in the sun, letting you know which of four levels of intensity the UV rays being emitted fall into.  A high level of intensity makes me sure to break out my highest SPF sunscreen and wide-brimmed hat.  However, just be sure not to let a low or moderate reading make you feel safe to go in the sun sans sunscreen!
