On April, 23, 2009, the
Virginia Department of Health (
VDH) was notified by
Virginia Commonwealth University (
VCU) that a Nuclear Radiation Developments, Inc. 'Ionotron' containing an
Am-241 source has been lost. The source is a model number A-001 with an activity of 20 microcuries on 12/75.
The source was last inventoried on February 27, 2009. Since then, VCU began to clean up this storage location and placing unwanted material in a barrel for disposal through RSO, Inc. The barrel was picked up on April 1, 2009.
VCU found the source missing when they went to take a picture for its disposal through the SCATR program. It is believed that the source was placed into the barrel and has been disposed of by RSO, Inc.
VCU will submit the 30 day written report to VDH.
This report is VA number: VA-09-01.
THIS MATERIAL EVENT CONTAINS A "LESS THAN CAT 3" LEVEL OF RADIOACTIVE MATERIAL
Sources that are "Less than
IAEA Category 3 sources," are either sources that are very unlikely to cause permanent injury to individuals or contain a very small amount of radioactive material that would not cause any permanent injury. Some of these sources, such as
moisture density gauges or thickness
gauges that are Category 4, the amount of unshielded radioactive material, if not safely managed or securely protected, could possibly - although it is unlikely - temporarily injure someone who handled it or were otherwise in contact with it, or who were close to it for a period of many weeks.
