- An integrating radiometer was used with two sensors to measure penetration of UVA + B and UVA radiation on August 7th and 8th, 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.
