We have conducted gamma radiation tests on our compressed sheet Styles 3000, 3200, 3400, 3700, 5500, 5507, 9800, 9850, and 9920. These tests indicate that our compressed non-asbestos styles will handle a total exposure of approximately 5 x 10E7 rads of gamma radiation. GYLON® Styles 3510 and 3545 have been tested, but are only resistant to approximately 1 x 10E5 rads. Test results are available upon request.
