Yes and no. It is true that a release of radiation, in isolation, is a one time thing unless you actually release some quantity of radioactive material. However, large amounts of ionizing radiation doesn't just vanish - when it is absorbed, in some cases it can either split an atom through fission or cause an atom to gain one or more nucleons through the absorption of neutrons, alphas, or whatnot. And in some of *those* cases, the resulting atom(s) is/are radioactive themselves. So, while the release of radiation itself may be a one time event, it may leave behind radioactive atoms in the environment even if it doesn't release any radioactive particles itself. Now, that takes a heck of a radiation flux, but still possible.
One of the assumptions I made was that the radioactive particles were contained. Apologies in advance if I wasn't clear on this assumption. I was under the impression that when the 'weapon' was fired it would expel radiation through an internal mechanism.
Alpha decay emits high velocity particles (He
2+), and they can be blocked by a sheet of paper.
Beta particles emit e
- or e
+, and they can be blocked by a sheet of tin foil.
I was assuming that our weapon was made of sturdier stuff than tinfoil and paper, thus my conclusion was that radiation was a one-time thing in this circumstance due to only gamma rays escaping.
Another assumption I made was that we weren't using absolutely silly amounts of nuclear power, reducing the likelihood of crazy amounts of ionization (and other bad things) in a given area where the 'weapon' is fired.

Why do people take Moores law as Gospel? It is not a LAW. Technology will not follow this "law" or system ad infinitum. Man make machine. Machine innovated over time due to new discovery, innovations, new energy sources and new science. These are driven by men, purely coincidentally and put forward at the rate of which it is put forward, which is no set system of time.
Moores "law" has already failed so I don't understnad why this is so commonly used in technology discussions.
Moore's law fails when it's interpreted to the letter (that is, as it was written
then).
People in the computer science community often argue to no end about this, but one popular interpretation of Moore's law is to look at computers in terms of raw performance (I.E. operations per second).
If you plot the increasing speed of computer processing over time, then an interesting correlation similar to Moore's law can be seen.
Though Moore's law is dead I would say the spirit of the law is still present in the advancement of computers (especially since the boom of parallel co-processors).
Keep in mind this is just my opinion.
I agree with you, though, on the reckless worship of Moore's law. It isn't really a natural law. It was just a clever observation made at the right time.
