... same way as echo sounding. Ultrasound penetrates the human body well, but some of the original wave is reflected off tissues, bones etc. The returned waves are used to build a picture of inside the body, for example in scans to check on babies while there are still in the mothers' womb ... in cardiology to detect heart damage and in ophthalmology to detect retinal problems. It is also used to heat joints, which relives some arthritic joint pain, and for such procedures as lithotripsy, in which shock waves break up kidney stones, eliminating the need for surgery. Ultrasound is noninvasi...

... blast created a maximum pressure of 35 tons per square meter, and maximum wind speed of 440 meters per second all while traveling through the air at 20.1 kilometers a minute. The heat rays projected from the mushroom cloud reached areas within two kilometers of the hypocenter caused all combustible materials to spontaneously do so. All of those fires in addition to that ... radioactively contaminated, that was sucked into the mushroom cloud, and came down for months after the bombing (The Atomic Bomb). The bombing on Hiroshima also had dramatic anatomic effects. The heat rays from the i...

... more fission reactions until all the material is scattered, or completely exhausted. This process releases enormous amounts of energy in the form of extreme heat and a massive shock wave. These nuclear explosions, in addition to their pressure waves, high winds, and flash burns, produce deadly radiation that contaminates soil and water, and destroyed living matter. The atomic bomb was first created in ... ...

... opened or closed. This could accur within ten miles of the blast. The nuclear blast is so strong that it just doesn't blow up then its all over, the multispectral heat blast (UV rays) which will come about a tenth of a second after the gamma blast. This blast would cause bleeding from every orifice of the body. The high winds, which accompany ... the pressure, wave. These waves will reach velocities of 70 miles per hour as far as six miles from the blast. Later people will begin to suffer from vomiting, skin rashes and an intense unquenchable ... ...
