About to go through Isaac, a little inland, so my family thought it'd be unnecessary to evacuate. As I prepare to lock myself in the inner most part of my house for the next few days, I'm wondering if Isaac will produce winds strong enough to break open my front door. Winds should be roughly 85 mph by the time it reaches me.
I just finished this great book called Radiation for Dummies and it told all about smoke detectors and dental xrays and the Van Allen Belts and why those guys that say we never went to the Moon are full of bat-turds. it seems that radiation doesn't just mean the green glow off of a meteor that is about to break open and a blobby alien comes out and eats San Francisco it actually is a bunch of DIFFERENT things. You got light. Light is radiation? Who knew? All light from really low frequency stuff thru microwaves thru visible light thru UV and XRays and Gamma Rays are ALL radiation! WOW! Its all photons and the shorter the wavelength the more energy and the really short ones like xrays and gamma are DANGEROUS! Smoke detectors don't emit Gamma, so you are safe from THAT. then there is a form that's just little electrons zipping thru the air and smacking you. These are pretty dangerous as they CAN penetrate your skin, but they don't zap thru you like X Rays do. A little metal stops them dead, like talking about evolution shuts up a preacher. there's also some big fat particles that are like the nucleus of a helium atom, but with a lot more energy! called Alpha Particles. These are the ones the smoke detector emits but only inside and they are stopped even by a SHEET OF PAPER! who knew? I mean all that comic book stuff is just lies! Too much radiation is like getting burned by a fire, sometimes from the INSIDE! You don't turn into any super-hero! Just a corpse.
no they generally dont nd den even if it is then it is so less that there is no effect on our body in fact our body emits radiaton too but we dont get affected coz its so less hope it helps..
air quality and procedures for being safe while working
Some smoke detectors - the ionisation type - use a tiny grain of a radioactive isotope called americium 241. This ionises the air in a small air space which makes it conduct electricity. If there is smoke in the air, the conductivity of the air space changes. The 241Am is not dangerous. It emits alpha particles, which have very low penetrating power. if you held it in your hand the radiation would not get through the outer dead layer of your skin. You probably wouldn't want to swallow it though.
