![]() ![]() Here are a couple other misconceptions about radiation and fallout… If hundreds of bombs were dropped on the Unites States it would be devastating to the environment, but most of the damage would last far after the radiation was gone. Or, 1000 rads decreases to 10 rads after 49 hours (7×7) The chart above shows the timeline.Īs you can see, when you watch movies like Blast from the Past where people spend years in a fallout shelter it just isn’t true. The 7/10 rule basically means that the radioactivity decreases by the power of 10 after 7 hours.Įxample: 1000 rads decreases to 100 rads after 7 hours. Radiation has a half-life, and without getting too technical about different kinds of radiation, most people use the 7/10 rule to calculate the decay rate. ![]() While this is true for the area where the detonation happened, it is not true for the outlying areas of the blast zone. Fallout & RadiationĪ misconception about nuclear fallout and radiation is that it hangs around for months or even years. There are quite a few factors that go into how much damage a nuclear strike will do, but anything inside 1 mile will be completely destroyed, and if you happen to be within 10 miles of the blast you might survive, but probably not for long.īomb size, weather conditions, wind direction and decay rate all play a factor in the residual damage radiation and fallout can do. has a list of nuclear bomb targets listed by state, Click here to see the targets in your area. Now that we know what kind of destruction to expect from these nuclear weapons we need to think about what targets are in our area. If 10 bombs are dropped strategical to produce the most damage, the situation will be completely different. If you live in New York and 1 bomb is dropped you might be OK if you are far enough away. Using the Nuke Map I linked too above will give you a good idea about what damages you can expect depending on how far from ground zero you are, but the one thing this Map doesn’t do is simulate multiple strikes. The bomb can kill or injure people through the initial blast of the conventional explosive, and then through the dispersal of the radioactive materials. You can set the wind direction, air burst or surface detonation, and get a good idea about how much damage each weapon will do.ĭirty Bombs: These bombs are what you might see from terrorists, a “dirty bomb” is a conventional explosive, such as dynamite or C4, with radioactive waste mixed in that scatters when the bomb goes off, but it is not a nuclear bomb. The website has what they call a Nuke Map which allows you to pick from several size nuclear bombs, and then detonate them (virtually of course) in your area. ![]() This article here explains the process in more detail. This fusion requires incredibly high temperatures. Without getting too technical it is the process of forming a heavier nucleus from two lighter ones. ![]() H-Bombs are nearly all achieved through the initial detonation of an atomic bomb or combination of fusion and fission. The bomb dropped on Hiroshima in 1945 was 15 kiloton’s, and the second, dropped on Nagasaki, was 20 kiloton’s.įusion: These are thermonuclear weapons or H-Bombs (Hydrogen Bombs) with extreme explosive powers are obtained through the process of nuclear fusion. Not only do you need to factor in the type and quality of the bomb, you need to factor in how many were used, and where they were used.įission: This type of nuclear weapon is commonly referred to as an Atomic Bomb, these can be as small as 1kt (Kiloton) up to several hundred Kilotons. 1 Kiloton = 1,000 tons of TNT, and 1 Megaton = 1 million tons of TNT… A little hard to wrap your head around right?įission vs Fusion: When it comes to nuclear weapons not all are created equal, this is why it is impossible to say exactly what might happen. Reference:A nuclear weapon’s explosive power is measured in yield, which is expressed in tons of TNT. ![]()
