Measurement of hydrogen concentration Measurement attention whether it will lead to new technology development safety measures

Hydrogen is the lightest gas on earth, is one of the flammable gas that burns when the concentration increases.Based on the fact that a large amount of hydrogen generated from nuclear fuel dissolved in the accident at the Fukushima Daiichi Nuclear Power Station in TEPCO has accumulated and exploded, the accident has become more serious, and has been developing technical development to measure the concentration of hydrogen as soon as possible.。In development, the lighter is focused on the faster the sound of transmitting the sound.The space full of hydrogen applies the characteristics of four times faster than the atmosphere, and has developed a device that instantly shows the hydrogen concentration by measuring the time when the sound is transmitted in a space containing hydrogen.The time required for measurement is 0.It can be used in a high temperature environment of less than 05 seconds and 350 degrees or more.The research group wants to take measures to prevent accidents such as explosions, as hydrogen may spread the use as a new energy replacing fossil fuels.Researcher, Aikuni, who was involved in the development, said, "When the development of social infrastructure using hydrogen is progressing, we can quickly find a slight leakage of hydrogen by using this technology, so we hope to contribute to safety measures."I am talking.
