anyway</font><font color="#CCCCCC"> so here the radiation</font><font color="#E5E5E5"> isn't</font> too bad<font color="#E5E5E5"> but there is some residual that</font> comes off the<font

is a good time</font><font color="#CCCCCC"> to</font> actually say something<font color="#CCCCCC"> about radiation</font> <font color="#E5E5E5">hazards you see the each one core over</font> there<font color="#E5E5E5"> all the reactor core is putting</font> out neutrons for science<font color="#CCCCCC"> you</font><font color="#E5E5E5"> have</font><font color="#CCCCCC"> for</font> research purposes<font color="#CCCCCC"> and there are two</font> sorts of radiation that you're worried <font color="#CCCCCC">about the first</font><font color="#E5E5E5"> is the sort of</font> electromagnetic which is essentially photons<font color="#E5E5E5"> very high-energy photons that's</font> the x-rays<font color="#CCCCCC"> and the gammas</font><font color="#E5E5E5"> and we all</font> know camera<font color="#CCCCCC"> here</font><font color="#E5E5E5"> with us you're the</font> world of good then an accidental overdose of gamma radiation alters<font color="#E5E5E5"> his body chemistry</font><font color="#CCCCCC"> and</font> <font color="#CCCCCC">now when David</font><font color="#E5E5E5"> Banner grows angry or</font> outraged a startling metamorphosis occurs <font color="#CCCCCC">but in reality</font><font color="#E5E5E5"> gammas can be stopped by</font> electrons and the heavier your nuclei <font color="#E5E5E5">the more electrons you get so basically</font> it scales<font color="#CCCCCC"> with mass the more mass you</font> <font color="#CCCCCC">have</font><font color="#E5E5E5"> the better your x-ray screening so</font> your typical piece<font color="#CCCCCC"> of x-ray screening</font> <font color="#E5E5E5">looks like that big piece of a concrete</font> in fact<font color="#E5E5E5"> from the reactor core here just</font> a couple<font color="#E5E5E5"> of</font><font color="#CCCCCC"> meters of</font><font color="#E5E5E5"> water will screen</font> most of the x-rays neutrons are a little <font color="#E5E5E5">trickier however because neutrons aren't</font> <font color="#CCCCCC">especially the fast ones</font><font color="#E5E5E5"> screened by</font> electrons<font color="#CCCCCC"> so the only way</font><font color="#E5E5E5"> you can really</font> stop<font color="#CCCCCC"> a neutron is to</font><font color="#E5E5E5"> actually capture it</font> with<font color="#CCCCCC"> a nucleus and when they're captured</font> <font color="#CCCCCC">so that's does</font><font color="#E5E5E5"> essentially what we're</font> <font color="#E5E5E5">doing with a helium-3 detector here the</font> neutrons<font color="#E5E5E5"> that come out</font><font color="#CCCCCC"> of</font><font color="#E5E5E5"> here have</font> <font color="#E5E5E5">almost no energy</font><font color="#CCCCCC"> so in order to actually</font> damage<font color="#E5E5E5"> living tissue</font><font color="#CCCCCC"> you need to be able</font> <font color="#E5E5E5">to break bonds and bonds are about an</font> electron<font color="#CCCCCC"> volt and energy so the neutrons</font> that<font color="#E5E5E5"> come through here</font> I only have about<font color="#E5E5E5"> a third of an electron</font> <font color="#CCCCCC">volt energy so I</font><font color="#E5E5E5"> don't really have</font> <font color="#CCCCCC">enough energy to even break</font><font color="#E5E5E5"> bombs</font> <font color="#E5E5E5">however there's a</font><font color="#CCCCCC"> problem</font><font color="#E5E5E5"> with neutrons</font> <font color="#E5E5E5">is that they're only got a half-life of</font> <font color="#E5E5E5">about 10 minutes and when they decay</font> they release about a mega electron volt <font color="#E5E5E5">of energy as a millionaire that</font> <font color="#CCCCCC">CommVault certain enough to break a</font> million bonds of living tissue<font color="#E5E5E5"> so it's</font> in many<font color="#CCCCCC"> ways it's like neutrons are like</font> <font color="#E5E5E5">grenades</font><font color="#CCCCCC"> you don't worry about</font><font color="#E5E5E5"> getting</font> <font color="#CCCCCC">hit by the grenade you worry about</font><font color="#E5E5E5"> it</font> exploded apart from<font color="#CCCCCC"> if you had a grenade and</font><font color="#E5E5E5"> it</font> goes bang I'd say grenade weighs about a kilo or something it makes<font color="#CCCCCC"> fairly good bang but if that</font> were the the the same mass of neutrons <font color="#E5E5E5">it releases a million times more</font><font color="#CCCCCC"> energy</font> so it'd be like a<font color="#CCCCCC"> thousand</font><font color="#E5E5E5"> times killer</font> <font color="#CCCCCC">time so you really don't worry about the</font> the neutrons energy itself<font color="#E5E5E5"> you worry</font> about what happens<font color="#E5E5E5"> when they decay</font> however neutrons can be<font color="#E5E5E5"> captured by</font> certain nuclei like<font color="#E5E5E5"> helium-3 and the</font> detectors<font color="#CCCCCC"> alright so we detect them</font> there but they can also be<font color="#CCCCCC"> stalked by</font> born<font color="#CCCCCC"> in boron-10 particularly so this is</font> like a rubber which is a lot of<font color="#CCCCCC"> boron-10</font> <font color="#CCCCCC">in it and</font><font color="#E5E5E5"> yet</font><font color="#CCCCCC"> any much of</font><font color="#E5E5E5"> it you can see</font> right and they capture<font color="#E5E5E5"> the neutrons and</font> then when they decay and they release <font color="#E5E5E5">this mega electron volt energy</font> <font color="#CCCCCC">it's just stopped by</font><font color="#E5E5E5"> the concrete which</font> means that me all the way<font color="#E5E5E5"> back here</font> behind<font color="#CCCCCC"> some more shielding another</font> instrument <font color="#E5E5E5">and some electronics that actually run</font> everything<font color="#E5E5E5"> that means that back here I'm</font> actually<font color="#CCCCCC"> pretty safe and that's the</font> reactor over there what I think<font color="#CCCCCC"> we'll do</font> to start<font color="#E5E5E5"> with is we're just going</font><font color="#CCCCCC"> to put</font> the iPod<font color="#CCCCCC"> not in the direct beam off to</font> the side<font color="#E5E5E5"> just</font><font color="#CCCCCC"> to see what it looks</font><font color="#E5E5E5"> like</font> you

The part I found most interesting about this video was the candid look inside a reactor facility. Frankly it looks kind of janky - dirty, random crap and tools spread all over the place, signs are ripped and crinkled, random wires and other equipment everywhere. Not that this is a bad thing, but just that it is not what I expected for a place that does super high end scientific research. I was expecting like a bright white clean lab with people in lab coats and masks and what not. Though that is probably just my stereotyped view from movies/tv of what it would be like. Cool video OP.

Engineers have better things to worry about than keeping things tidy. I always find my workbench under a pile of wires and other things. Look like an electronics factory exploded.
