cause and effect of bombing?

(m)\n\nON THE 6th August 1945, exactly 56 years ago, an atom bomb destroyed Hiroshima. Nagasaki faced devastation three days later. The Imperial Headquarters requested Dr. Y.Nishina (famous for Klein-Nishina formula for Compton scattering of photons) to go to Hiroshima. He concluded that the damage was due to an atomic bomb. \n\nWhen the bombs were dropped, these cities had an estimated population of 310,000 and 250,000 respectively. About 90,000- 140,000 in Hiroshima and 60,000- 80,000 people in Nagasaki died immediately or within two to four months after bombing, resulting from collapse of houses caused by the blast and from heat rays and fires and radiation exposure. In the 1950 Japanese national census, nearly 280,000 persons stated that they "had been exposed" in the two cities. \n\nRadiation fogged X-ray films stored at the Hiroshima Red Cross Hospital. Exposed material became radioactive. Kimura and Tajima of the Institute of Physical and Chemical Research determined that the Hiroshima bomb exploded at a height of 577 m. They used an electric furnace and a carbon arc furnace to simulate charring observed on the surface of a wooden board of Japanese cypress and estimated that the bomb had a radiant energy of 4.6 million million calories. \n\nScientists could enter the bombed area only after 3 to 4 weeks because of frequent typhoons. They measured higher radiation levels due to induced radioactivity near the epicentre. Additional radiation levels were 10-15 per cent of the natural background. \n\nOn November 18, 1946 Harry Truman authorised the National Research Council to establish an agency "to undertake a long range, continuing study of the biological and medical effects of the atomic bomb on man". This organisation grew into the Atomic Bomb Casualty Commission (ABCC). ABCC continued to work till 1975 when Radiation Effects Research Foundation (RERF) was set up as a bi-national endeavour. \n\nMany believe in the myth that birth defects are more common among the children of the survivors of the atomic bombings at Hiroshima and Nagasaki. In my interaction with general physicians and other professional groups the one topic, which elicits maximum queries, is " genetic effects of radiation". Radiation can cause mutations in genes. Mouse and in fruit flies exposed to radiation suffer genetic mutations. The changes may show up in the offspring as colour of the coat, shape of the wings, etc. But such markers are not available in the human species. We require very sophisticated laboratory methods to demonstrate subtle changes in exposed individuals. \n\n\nPhysicians appointed by ABCC examined 76,626 infants conceived and born in Hiroshima and Nagasaki over a period of six years starting from the late spring of 1948. The researchers did not see statistically demonstrable increase in major birth defects in these infants. While the survey started, certain dietary staples were rationed in Japan. Pregnant women had special provisions. Because of this, the surveyors of new-borns could identify 90 per cent of the pregnancies that persisted for at least 20 weeks of gestation. \n\nPhysical examination of the new born and autopsies on as many stillborn infants revealed that neither the frequency of major birth defects nor the frequency of the most common birth defects differ significantly with radiation exposure of parents. The researchers examined some 21,788 infants shortly after birth and re-examined them eight to ten months later. The study covered 65,431 registered pregnancy terminations and appropriate control populations. \n\nIn a brief review, the Radiation Effects Research Foundation cautioned, "The absence of a statistically significant effect of ionising radiation on the frequency of major birth defects should not be construed as evidence that mutations were not induced by parental exposure to atomic radiation". The researchers saw mutations in every animal and plant species studied. \n

Take a look at the pyrotechnics chapter of this side.\n\nhttp://www.vk2zay.net/\n\nCareful: it is neither simple nor without danger.

Humans invented hydrogen bombs which are filled with highly reactive hydrogen.On blast this nasent hydrogen reacts with oxygen present in the air,this produce water.\nThis reaction cause all breathing living things die on the spot because the lack of oxygen.

I'm not to sure of this ,but I think I once read somewhere\nabout bomber crews of the R.A.F. and the U.S.A.A.F.(as it was then)reporting strange looking aircraft that they saw in European skies,try the reference library,a fascinating subject,best of luck with it

Wikipedia has a complete overview of it; including causes and the aftermath. I linked it below for you.

No, not yet. But the media hounded them to be released to the public and that's where the item about making a bomb came from. It was in the news right before the election.

The effect of the bomb depends on how big it is. The major effects are blast, heat and radiation, and they would reach out from "ground zero" depending on the size of the bomb. London is a big city, so very likely the effects would be limited to London, not the whole of England.

Russia dropped!!!!from an airplane this hugh super H-Bomb...it was meant to scare the US. There is a video of it on the net somewhere. It was the biggest one set off..I found a link to it below

The fiasco on the interstate caused me to miss my flight. The formidable fortress stopped the attack by the Egyptians. The seeds of the plant always germinate during spring. The conflict escalated into war when the Soviets fired a nucleur missile. The cheerleaders were effervescent when their team scored a touchdown.\n\n\nHope it helps...

I use to work in IRAQ as a Contractor Engineer for Haliburton and have seen the destruction and loss of life because of roadside bombs first hand. This is a very good question. However, there are multiple answers primarily because there are many types of IED's (Imprevised Explosive Devices) being used for roadside bombs.\n\nEach type of bomb can be made of different explosive material (dynamite, C-4, fertiiizer, gasoline, etc.). the explosive material is covered with nails, metal shavings, BB's, bits of broken glass, and anything else they can scavange to cause death. In addition, there are many types of triggering devices used to detonate the bombs (electronic, mechanical clocks, fuse, impact/contact, etc.)\n\nNow to answer your question a scanning camera can be used but it is just that - a scanning camera. These cameras only give you a visual of an object. While on a convoy to transport food, water, medicine, fuel, war materials or people, the roads from the green zone (safe area) to the red zones (anywhere outside the green zone) are very long and are used by regular Iraqi citizens. You can't tell whou is a friendly and who is an insurgent. You don't know if a person is bending over to tighten the foot strap on his sandal or placing a bomb. A bomb can be placed there one day and removed the next. They (the insurgents) don't know when our convoy's are going to run, but they do know the major raods we use. \n\nDuring the war we bombed the hell out of towns and roads. These roads are littered with all kinds of debris, large stones, metal objects, tires, used water cans, wooden crates, abandoned cars, trash piles, and thousands upon thousands of tiny sand mounds. If we were to use a scanning camera we would get just a visual of the object. In order to detect the material within the object requires a special camera with special equpiment to find the explosive material. The problem here is that different cameras are needed for different types of explosve material.\n\nTo find IED's a humvey would have to loaded with thirty different types of cameras and detection equipment, each with their own power source. Each vehicle of this type woud cost about a million dollars per vehicle. Even then the success rate would only be about 20 - 40 percent accurate. Sand storms happen all the time (day and night) and come up out of nowhere. These storms impair the vision of the cameras making them even less effective. Using infra red doesn't work because most of the IED's used don't have a heat pattern, and the heat generated by the triggering device is the same size as sand bugs or beatles commonly found in the desert. There are millions and millions of these. \n\nIRAQ has thousands of roads we use and the cost would be prohibitive. In addition, this vehicle would inevatibly have to be the point vehicle in the convoy, and searching for IED's is a very, very, very slow process. This makes this vehicle a prime target for a low tech bomb (fertilizer and ammonia), a RPG, or snipper attack. Once this vehicle was taken out by the insurgents the rest of the convoy would be sitting ducks. This is why you see on the news that convoys are driving down roads at an accelerated speed hopping to drive past the IED's before they explode.\n\nFor the remote controlled IED's some (not all)our vehicles do have RF (radio frequencey) jamming devices to scramble the signal used by the insurgents to remotely trigger the device. But because these are typical garage door type triggers, there are thousands of frequencies and sub-frequencies that can be used. On a daily basis the Army Corp of Engineers does a RF signal sweep using a specrtun analyzer to determine which frequencies are in use, and we tune our jamming equipment to those range of frequencies. This kind of works but it doesn't work against triggers that use cell phones, fuses, or impact triggers.\n\nTo make things more complicated Iraq is a very large co

It has it's flammable state...Try to imagine it as a fuel air bomb.Thn there you will get your Idea.

Bombing is pointless they built there facilities with our bombs in mind. Thus any attack would be worthless as the facilities are way underground and well armored. Invasion as Iraq proved is quite out of the question. The best response is to let them have there toys and let them know that they have now made themselves targets for our nuclear arsenal. This kind of deterrence has worked to keep nuclear powers in line before and will again. No matter if the govt is full of religious or political fanatics in the end they are human and don't want to die if it can be avoided.

They are doing work with lasers on effecting weather and often people have 'cannons' for hail with the idea that the sound waves will break up the ice. I'm not sure about bombing the storm. Storms are created by a range of factors that would not be all effected by a bomb. The website is complicated but talks about the use of high frequency waves to achieve this. most military applications are to do with clearing fog etc...to allow for a strategic advantage.
