An integrating radiometer was used with two sensors to measure penetration of UVA + B and UVA radiation on August 7^th and 8^th, 2013 in Austin, TX. The percentage of radiation that penetrated into the interior of the containers was calculated by integrating the energy over a ten minute interval in the sunlight without anything blocking the sensors (value inside of brackets), and then placed into the sealed containers for ten minutes. J = joules.
