100Mev+ X-Ray &#x2F; Gamma radiation is not fun. There is some play in the numbers based on type of fusion, but ~1w is on the order of 10^12th reactions per second and flat out lethal. Sure, if a device is weak out 1 millionth of that then it&#x27;s not a big deal, but nobody cares about 0.000001 watts &#x2F; second.
