New Shipping Regulations For Detectors Containing Boron Trifluoride

In April of 2007, the US DOT issued a letter of interpretation to LND regarding the shipment of BF₃ detectors.  The letter states that LND's neutron detectors containing less than a gram of BF₃ at less than an atmosphere of pressure are no longer subject to the hazardous materials regulations.

In May of 2007, the US DOT issued a letter of clarification to LND.  In our request for clarification, we asked them to address the issue of transporting the detectors inside portable instruments.  The letter of clarification states that when the detector is inside a moderating sphere (REM ball) it is not considered hazardous and is not subject to the hazardous materials regulations.

If you purchase a detector that contains 1 gram or more of BF₃ or that is filled to atmospheric pressure or greater, the detector must be shipped as hazardous material using US DOT Special Permit 12087.  If it is shipped internationally, then LND's A2 Competent Authority Authorization must be used in conjunction with Special Permit 12087.  The links for these documents may be found below and in our FAQ's section of this website.
