mr. trimble to respond to a few questions. you report included in it and number of visuals that were especially interesting. we have taken three of those photos and put them on these large charts. these present each of three to you in sequence. i want to ask you to describe the photo and a security concern that it represents. here is the first one. what is the photo of? >> this is one of the sites we visited. it is a warehouse storing radiography cameras. the potential vulnerability here is the large doors openly left -- is obviously left open and unattended. >> all right. what is inside that might be of interest? >> these are the radiography cameras that you had the earlier picture of. centraluse would be the location where these cameras would be stored when they are not out in the field being used. >> could be two or three or maybe a couple of dozen? >> in this case they would be in a storage room behind a locked container. because they were in a locked container, they are meeting security requirements. open doornding the an

mr. trimble just said to? >> i would like to take perhaps one of his points just very briefly and what of mr. mr. satorius' point which is coordination and an area where we can play a special role along with nrc and dhs. reaching out to enforcement can often be very complicated. there are many different layers. you might need in a tribal area. it might be a university campus with its own security police. it could be in an environment where you have local county and state police cell part of what we do collaboratively to go above and beyond the actual rule is to organized daily exercises that involve all components of the community. these exercises really help bring together the different elements of the community that would be involved in response to any kind of incident and so far the cooperation with our colleagues at the department of energy could you conjure terrorism and counter bluff ration we have run well over 100 of these exercises all over the united states and communities. >> how often? see several
