Technically, humans can withstand that much pressure, but most people would be killed by falling buildings. If you somehow survive all of that, there's still the radiation poisoning to deal with – and the nuclear fallout. WebDefinition. 1 Bq = 1 s −1. A special name was introduced for the reciprocal second (s −1) to represent radioactivity to avoid potentially dangerous mistakes with prefixes.For example, 1 µs −1 would mean 10 6 disintegrations per second: 1·(10 −6 s) −1 = 10 6 s −1, whereas 1 µBq would mean 1 disintegration per 1 million seconds. Other names considered were …
