7/26/2023 0 Comments Cobalt bomb first strike![]() Windows will shatter as far away as Santa Monica (~18 miles away). Beyond here, you'll get damage to everything out to Beverly Hills and Panorama City.This would include Universal Studios and parts of North Hollywood. Out to 4.50 km (2.81 miles), any ordinary house is gone and reinforced structures are going to be severely damaged. ![]() Nothing is going to survive on the surface. Sinai Memorial Cemetery and a couple of parks, will just be gone, reduced to atoms. Within 2.45 km (1.53 miles), most of Burbank, including our target, the Mt.The following things will probably happen: 10 psi of overpressure equals your building getting hit by a 470 km/h (294 mph) wind. This is measured in terms of the sudden increase in pressure. The problem consists of the fact the object you were standing behind is now on fire with all that entails. You will have a problem if you are standing behind something more combustible like, say, a heavy curtain since the object you are standing behind absorbs the heat from the pulse instead. If you are standing behind a concrete wall at, say, 5 kilometers and somehow are unscratched by the shockwave (see below) then it may feel like you are in a oven for awhile but you will come out just fine. It should be noted that the thermal pulse will travel in a straight line. Some reports claim that 50% of deaths at Hiroshima and Nagasaki were due to flash burns, though the methodology of separating these from the burns caused by the firestorms - which caused the bulk of the deaths - is dubious. In and around ground zero itself, an area roughly a half-mile across, the temperatures will (for a few seconds) be hotter than the sun! If you're sunbathing on the beach, you're toast in both senses of the word. If you're within 11 km (7 miles) (Beverly Hills), you're going to get a bad sunburn on exposed skin. That's not the worst of the problems - there is also thermal radiation to consider. But heaven help you if you look up at the sky while the bomb goes off. ![]() Unless you're Sarah Jane Smith, and probably for her too, this is not good at all. This is very, very bright and if you are close enough (21 km (13 miles) on a clear day and 85 km (53 miles) at night for a 1 megaton nuke) will cause at least temporary flash blindness. The first thing you get with a nuclear explosion is the light flash. But we want to give a reasonable explanation for this article, so we'll use the simpler explanation of a ground burst. ![]() note Low-yield ground bursts might be militarily useful if the objective is to limit the radius of destruction, target military infrastructure with minimal collateral damage to nearby population centres, or to do things like deeply and irreparably crater a site - but the enhanced fallout would be a high cost. note What, you thought we'd let you get away with Hannah Montana? This is what is called a "ground burst" and is easier to estimate the damage and casualties than an air burst, but it should be noted that if nuclear weapons were to be used for military purposes (and the two times they were used) the explosions will all but certainly be air burst. 500 South Buena Vista Street, Burbank, California ( Lat 34.155744, Lon -118.326766 note You can follow along here on Google Maps if you like note or use this handy-dandy simulator ) will be ground zero and the bomb will detonate on the ground. For this discussion, we will detonate a 1 megaton nuclear weapon in Los Angeles.
