 The product was really developed as a result of conversations we had with our customers in the petrochemical industry. They had a process challenge, a very difficult process that they needed, a reliable measuring instrument to give them control of the process. We brought the idea back, set the challenge to our physicist team and as a result of that they did some brilliant innovative creative working in the science to come up with a perfect measurement solution to that process challenge. The physicist we employ are right at the heart of our innovation process. We always face a challenge with process plans of being able to deduce what's happening behind the steel walls of the vessels and the pipes that go to make up the process and by employing physicists we're working with the core detection sciences that allow conditions behind those steel walls to be accurately measured and if you can measure it you can control it and that's the goal that the operators of those plants have. It gives multiple benefits to our customers. The most important one is that it isn't fooled by solid buildup. When it sees solid buildup it recognizes that it allows the operator to measure the solid buildup but never loses sight of the bulk liquid level in the vessel. The product uses gamma radiation by transmitting a gamma signal from one side of a vessel from a small radioactive source we can call that an emitter through the vessel and through the vessel contents to a very sensitive detector array on the other side of the vessel. The gamma radiation is attenuated according to the process media it's passed through so the denser the process media the more radiation gets blocked and doesn't reach the detector. From that you're able to deduce very accurately what process media the gamma radiation has passed through. For broader society the benefit is that those process operators producing products that are vital to modern society get to produce a better conforming product consuming less energy for less cost and that on a macro scale gives a massive overall benefit to society. We currently have big plans to expand the tracerco business in the northeast. The most exciting development in recent years is our investment in a new multimillion pound measurement technology center being built right here at Billingham. Winning the Institute of Physics Innovation award is a tremendous boost for tracerco. It's particularly good that it brings light and prominence to the tremendous work that our scientists do in the background in the development of all the products that we take to market. This award is an opportunity for us to bring prominence to that hard work and also give everybody in the company a chance to feel proud.
