There we go. Sorry about that okay. What was our methodology for parcel a1. We had three main ideas when we started our survey. First was were going to do a walk over survey scan. This takes a lot of physical work and this was a large, 50 acre parcel so show you the instruments and how we did that walk over it scanned survey. We also employed what we call a scanning system. It is a fourwheeldrive vehicle the pulls a trailer. It has two very large volume sensitive sodium iodine detectors. Theyre connected to a laptop, and every second is conflicting a piece of data as to what is beneath that detector. Any anomalies we would found would go back and check with another instrument that i will demonstrate in a few minutes. This is going the wrong way. Parcel a1 is constructed of survey units. They were composed of all kinds of different natural materials, manmade materials. You have different wood chips and clay material, you had different degrees of vegetation, different types of rocks such
Spot almost 35 hours just to receive the same radiation as a flight. We thought that would help folks put the radiation levels in context. The source was removed by the navy contractor, and then, we surveyed the soil after it was removed and no residual contamination was found. This is the spectrum that i was talking about before. The one on the right is a picture of mother nature. You can see a little peak at the bottom. These are all radio active materials, and this is what matter nature looked like. Before the source was removed, we used our falcon 5000, and you can see that peak on the left. It goes straight up. Thats raidium 226. The detector sees that fingerprint and plots it on the spectrum. So the spectrum on the right is after we removed the source, and thats back to mother nature. The low energy peak, so after we had completed parcel a1 survey, late october, early november, my staff went back to the office and started combing overall the data. And one of the Staff Members dis
An anomaly. The top instrument is a falcon 5,000. Uses a high purity geranium detector. The bottom ways is called the inspector 1,000 which uses a bromide detector. Both of those instruments are able to generate a spectrum. Think of it as a fingerprint. Both these instruments can see whatever gamma rays are coming off the ground, from whatever natural or manmade radio radioisotopes are there. Each isotope has its own fingerprint, so the spectrum literally visualizes each fingerprint for each radionuclide in the soil. So if we found an anomaly, and i can discuss anomalies later, if we found an anomaly, we would go to the spot, and we we do use the inspector 1,000 and set the detector on it for 30 minutes. It is a long count time. We would generate a nice looking spectrum, and then from that spectrum, using the fingerprint knowledge, we know what is president present in the soil overall, here is a demonstration , a visual of our staff using the inspector 1,000 on an anomaly. There were 1
Nbcs sarah dalof starts our coverage tonight. Reporter on the first day of a newly established route monday morning, tragedy aboard amtrak 501. Things started to tip over and as it was going around and then all of a sudden just ended up on side, and everything went dark and stuff started flying around and that was it. Then it stopped. Reporter a stunned motorist watched the train derail. One car falling to the interstate below, another dangling from the overpass. I was right in front of it really. Nerve racking, kind of sick to your stomach after seeing this right now. Reporter multiple vehicles were hit by the falling train car as others came crashing into the pile. The people that were in all the vehicles, even though when you see the pictures, its pretty horrific. At this point nobody in any of vehicles was fatal. Reporter 77 passengers and five crew members were on board the train which was headed south from seattle to portland. Witnesses scrambled trapped survivors and help emerge
Us live at the site of the smoke off of 580. Tell us now what that air quality is like. Reporter well, the air quality is much better than when we first arrived and still dont know what caused this fire. As you can see theyre still pouring water on the flames and the shelter in place is still in effect. Thick black smoke can be seen for miles. I drove through a cloud that looked like fog. When i went through the freeway just now, it was so thick. You could taste it and you can taste it now. Its not as bad here but its coming this way. Reporter robin casey receiving two shelter in place alerts tonight. Currently a shelter in place due to heavy smoke from a fire. Reporter the fire started just after 5 00 underneath a pile of scrap metal at the recycling facility. Richmond fire ordered an immediate sheetner place in five neighborhoods. Santa fe, atchison village, north richmond, west of the Iron Triangle near richmond parkway. Its important folks stay inside. Reporter fire officials says
