Hi Michael, At TVA's Sequoyah plant we use the DMC-2000GN electronic dosimeters to monitor neutron dose during dry cask campaigns (this is the only significant neutron dose source we have due to our plant design). We have not experienced any unusual neutron doses or dose rates with their use during any of the last 3 dry cask storage campaigns. These units have not been used outside this work activity, so we cannot speak to how they perform in "non-neutron areas." Jim

Please use caution when opening. Has another utility experienced unusual neutron spikes response when using DMC2000GN dosimeters in non-neutron areas? We have experienced several unusual neutron doses and dose rates within a short time after activation of the DMC2000GN.
