In nuclear physics and nuclear chemistry, nuclear fission is either a nuclear reaction or a radioactive decay process in which the nucleus of an atom splits into. Smoke from bushfires such as this relatively small one on the suburban fringe of Sydney can substantially reduce the amount of sunlight reaching the ground for short periods. We will all go together when we go. Every Hottentot and every Eskimo When the air becomes uraneous We will all go simultaneous Oh, we all will go together when we go. Tom LehrerIn the following article Dr Brian Martin, without belittling the horrendous effects of nuclear war, dispels a little of the gloom surrounding the subject from Australias point of view at least by arguing that contrary to Tom Lehrers assertions we may not all go together when we go. While a full scale nuclear war would devastate some parts of the earth, particularly in the northern hemisphere, present evidence indicates that nuclear war poses no threat to the survival of the human species. Ever since the first nuclear bomb was exploded at Alamogordo, New Mexico, on 1. July 1. 94. 5, the threat of nuclear war has existed.

Today the United States possesses some 3. Soviet Union some 2. China, France and Britain several hundred to a few thousand each. A few other countries such as Israel have or may soon have small nuclear arsenals. The Hiroshima and Nagasaki bombs killed a total of perhaps 3. What would be the result of all out nuclear war using todays weapon arsenals This question has become more important in many peoples minds in the 1. In the immediate vicinity of a nuclear explosion, most casualties result from blast, heat and fallout during the first few days. The blast or heat from a one megatonne bomb about 7. Hiroshima bomb, and a size often found in nuclear arsenals would kill almost all people, even those in shelters, out to a distance of two kilometres. Beyond ten kilometres the chance of death even for people without special protection would be very small. If the bomb is exploded at an altitude higher than the radius of the fireball from the explosion, as happened at Hiroshima and Nagasaki, local fallout is minimal. If exploded at or near the earths surface, fallout lethal to unprotected people will be deposited downwind most often to the east toward which prevailing upper atmospheric winds blow for a distance of up to hundreds of kilometres. After a fortnight the radiation levels will have dropped to about one thousandth of what they were one hour after the blast. A major global nuclear war could kill up to 4. United States, Soviet Union and Europe, and to a lesser extent China and Japan. The death toll would depend on a range of factors, such as the areas actually hit by weapons and the extent of evacuation and fallout protection. This death toll would be made up mainly of the people in the immediate vicinity or downwind of nuclear explosions, and would total about ten percent of the worlds population. This figure would be much higher if most of the largest population centres in countries all around the world were bombed,5 but there are no known plans for systematically bombing the largest population centres in areas such as India, Southeast Asia and China. On the other hand, if a nuclear war were limited in any sense for example, restricted to Europe or to military targets the immediate death toll would be less. If agricultural or economic breakdown or epidemics occurred in the aftermath of nuclear war, many more people could die, perhaps as many as a few hundred million in the worst case. These would be primarily in the most heavily bombed areas, namely the United States, Soviet Union and Europe. Nuclear war would also result in various long range effects, beyond the range of blast, heat and local fallout. These effects effects hundreds or thousands of kilometres from nuclear explosions are known as global effects. The most well known is global radioactive fallout. Many people believe that this fallout, or some other effect, would cause the death of most or all the people on earth in the event of major nuclear war. This is the idea portrayed in the popular novel On the Beach. However, the available scientific evidence provides no support for such a doomsday scenario. My aim here is to describe in general terms the main global effects of nuclear war with direct consequences for human health. Four main categories will be treated global fallout,9 ozone, climate and fires. Global fallout When a nuclear bomb is exploded, energy is released by the fissioning splitting of either uranium 2. There are a range of products of this fissioning, many of which are radioactive that is, they are unstable and decay sooner or later by emission of energetic radiation or particles. The most well known fission product is strontium 9. About half the strontium 9. Different radioactive atoms have different half lives, ranging from a fraction of a second to many millions of years. Other biologically important radioactive species produced by nuclear explosions are caesium 1. A nuclear bomb like that exploded over Hiroshima produces a total of about 8. The enormous heat generated by the explosion creates a huge upwards surge of air, resulting in the familiar mushroom cloud. The height of the cloud depends on the size of the explosion1. Figure 1. Most of the fission products are carried into the atmosphere by this initial updraft. They become dangerous to humans when they return to earth. Figure 1. A typical configuration of the troposphere and stratosphere divided by the dashed line in July. The approximate heights of clouds from nuclear explosions of 2. Mt and 2. 0Mt are sketched widths are not to scale. The dotted line is a typical distribution of stratospheric ozone. If the bomb is exploded at or near the surface of the earth, a large amount of dust, dirt and other surface materials will also be lifted with the updraft. Some of the fission products will adhere to these particles, or onto the material used to construct the bomb. The very largest particles stones and pebbles will fall back to earth in a matter of minutes or hours. Lighter material ash or dust will fall to earth within a few days, or perhaps be incorporated in raindrops. The radioactive material which returns to earth within 2. It is the most dangerous. As mentioned earlier, the fission products contain a mixture of different types of radioactive atoms, some of which decay quickly and others much more slowly. A rough rule of thumb is that as time increases by a factor of seven, the average decay rate drops by a factor of ten. Thus, compared to the decay rate one hour after the explosion, the rate will be about ten per cent at 7 hours, about one per cent at two days about 7 x 7 hours, and about 0. After about six months the fall in the decay rate becomes faster than this. For this reason, exposure to early fallout is the greatest danger due to radioactivity generated by nuclear explosions. Radioactive material which takes longer than 2. Some of the delayed fallout remains in the troposphere see Figure 1 for days, weeks or months. This tropospheric fallout usually returns to earth within ten or 1. The clouds of nuclear explosions larger than about one megatonne penetrate partially or wholly into the stratosphere, and deposit fission products there, which become stratospheric fallout. Since the stratosphere has no rain formation and is less turbulent than the troposphere, radioactive particles in the stratosphere can take months or years to return to earth. During this time the particles can move to any part of the globe. By the time stratospheric fallout reaches the earth, its radioactivity is greatly reduced.
