Bananas are made out of potassium-40 which produces positrons as it decays. The antihydrogen gets stuck in the area with the weakest magnetic field. Such a wave can be catastrophic depending upon its intensity. This makes it incredibly hard to store antimatter. The blast radius for the 1 kg bare explosive detonation is 130 m. This answer is obtained by using the range safety equation, based on Hopkinson-Cranz Law: R = 130 W(1/3) = 130 1(1/3) = 130 m The intensity of the blast wave front is inversely proportional to the cube of the distance. We have a mole of atoms in a gram, or a total energy release of (2 GeV)(6 x 10^23)(1.6 x 10^-19 J/eV) = 2 x 10^14 J, or 200 terajoules.

But that would miss all the boats, planes and submarines crowding their primitive buoyancy based transportation lanes. 10 grams of antimatter will annihilate 10 g matter, which just produces 429.6 kT. Lowest tech level to blow up the solar system, Counting and finding real solutions of an equation, A boy can regenerate, so demons eat him for years. Ten things you might not know about antimatter The approximate total yield of the super-eruption of the. Back To Anycalculator.com E = mc^2 Each gram of antimatter will release roughly twice as much energy as the Hiroshima bomb. I was planning on adding more to this response, but I think Serban covered it as well as I can for numbers #1 and #2. If you want to kill all humans on earth, you have a couple of options: According to this person 57 trillion annihilations at 30 cm gives you 1 rad of radiation. The problem you'll quickly run into is that the Earth is big. During this interval, the pressure rises abruptly to a peak value and then decays exponentially over time. Using the convention that 1 kiloton TNT equivalent = 4.18410 12 joules (or one trillion calories of energy), one half gram of antimatter reacting with one half gram of ordinary matter (one gram total) results in 21.5 kilotons-equivalent of energy (the same as the atomic bomb dropped on Nagasaki in 1945). Use MathJax to format equations. In other words, for each gram of TNT exploded, 4.184kilojoules (or 4,184 joules) of energy are released. But case 2 deserves a better answer after all anti-matter is not cheap and they are always out of stock at Home Depot. With careful planning, I expect less well less than 1 gram of antimatter would be needed to make this a bad day for the earth. On the other hand, one milligram of 18F-FDG will contain on the order of 3x10^18 molecules. Still a big bang. You can maybe kill everyone with less antimatter if you settled for giving everyone cancer instead. TNT equivalent is a convention for expressing energy, typically used to describe the energy released in an explosion. Antimatter - Wikipedia Using the convention that 1 kiloton TNT equivalent = 4.1841012 joules (or one trillion calories of energy), one half gram of antimatter reacting with one half gram of ordinary matter (one gram total) results in 21.5 kilotons-equivalent of energy (the same as the atomic bomb dropped on Nagasaki in 1945).
