Attachment 13 Government Furnished Property
The following Government Furnished Property (GFP) may be available for new Radiation Portal Monitor (RPM) procurements.
GFP He Tubes in Inventory The availability of GFP-supplied Helium 3 (He3)-based neutron detector tubes cannot be assumed, so vendors should have a non-Government furnished neutron detection capability that will be validated through Government testing.
Table 1 lists all of the He3 tubes currently in inventory. At any time, the number of any model available to the vendor will vary.

GFP Inventory Sensor Enclosures The current inventory of Government sensor enclosures are provided below. Re-used GFP sensor enclosures will require verification that they continue to meet National Electrical Manufacturer Association (NEMA) 4 requirements after re-use. Table 2 lists the sensor enclosures by model.
