Saudia Arabia. Sealed sources: New York State Department of Health requires leak checking ( I call it an integrity check) of beta sources of less than 100 uCI and alpha sources of less than 10 uCi. The test will be sensitive enough to detect 0.005 uCi. I hope that is simple enough. Bob Ryan St. Peter's Hospital 315 South Manning Blvd Albany, NY 12208 ryanchp@aol.com
