Electromagnetic radiation in the UV range of the spectrum cannot be perceived by the human eye. Using the Neulog™ UVB sensor specifically designed to measure UVB radiation, you will compare the amount of UVB radiation reaching the sensor. The sensor will be protected by both SPF15 and SPF30 sunscreens to determine if the sunscreens actually provide UVB protection and if so, how much protection. There are enough materials for 15 set ups.
