Using Neutron radiation from Aluminum foil is this Legal to do?

I am wondering if I expose plants to Neutron radiation and carefully burn them afterwords.at 500 deg C is this safe and more importantly is it Legal?? I plan to use a 4% thorium Rod (Welding Rod). What about Beta and gamma radiation is this Legal. I heard on youtube it is as long as you Properly dispose of the seeds.  I did a similar Project with clover a few cm away from a total of 20,000 volts 35 mA power supply and dosages above 400 volts per meter squared killed the clover plants very quickly. I sterilized the soil and seeds with bleach and incinerate it with High heat 500-600 degrees C. I washed by draining most of the bleach out of the seeds.

What could be inside of this? It is something for removing earth's radiation? Answered

What can be inside of this (Attachment) ? It should be a device you put under your bed to neutralize health effects of Hartman and Curry grids - Earth radiation. I am guessing a simple coil, but what is happening if you connect it to the power outlet's ground? What do you think about it? Is this bogus device, and would there be a way to neutralize those radiations? (I do not have this thing, I just want to prevent my father from wasting $50... by the way there are no possible returns)

Ionizing vs. non-ionizing radiation, units, and safety (updated)

Note: This was originally intended as a reply in the Americium-241 Science forum topicWhen people talk about "radiation," they are referring to many different things, and are probably thinking of some things that don't even apply. "Radiation," the invisible energy given off by radioactive materials, can be either "subatomic" particles or electromagnetic. The most common particles emitted are "beta rays," high-energy electrons, and "alpha particles," helium nuclei. Some sources can emit neutrons, protons, or "positive beta rays" (anti-electrons, or positrons), but those are much less common.The units we use to measure radioactivity are becquerels (Bq, decays per second) or curies (Ci, 3.7 x 1010 decays per second). Since the effects of radiation depend on their energy, another unit of interest is absorbed dose, the energy deposited per unit mass of target, measured in grays (Gy).Safety experts classify radiation into "ionizing," meaning there is enough energy to knock electrons out of atoms or molecules, and "non-ionizing." Infrared and ultraviolet light are non-ionizing, as are neutrons. Alpha particles (helium nuclei), beta particles (electrons) and gammas (as well as lower energy X-rays) are all ionizing radiation. The three have substantially different effects on biological systems, even at the same absorbed dose. Consequently, for radiation safety purposes, scaling factors are applied to produce numerical measures (sieverts, Sv) of "effective" or "equivalent" dose, that can be compared across different kinds of sources.Here's a small table with information for some commonly encountered sources. Isotope Source Activity Dose rate Am-241 smoke detector 35 kBq (1 µCi) 11 µSv/yr @ 1m Te-99m MRI contrast 740 MBq (20 mCi) 1.6 Sv/hr @ 1cm C-14 atmosphere, body 0.23 Bq 10 µSv/yr K-40 bananas, body 4.4 kBq 200 µSv/yrWhat you should see clearly from this is that the natural radioactivity in your body is comparable or larger than that in a common smoke detector. At SLAC, the limit for exposure to sources at the lab by most staff (including me) is 20 µSv/yr (5 mrem).As I noted above, neutrons are sometimes lumped in with ionizing radiation in non-technical "radiation safety" classes (we call them "the photon is your friend" training :-). That is not really accurate -- neutrons don't interact with electrons(*), and so cannot ionize directly. They can interact with hydrogen nuclei (protons), knocking them out of complex organic molecules, and leave behind ionized fragments and free radicals. The can also be absorbed by otherwise stable nuclei, making them radioactive; those new nuclei may in turn give off ionizing radiation.Neutrons lose energy much more slowly in passing through material, and so can penetrate much farther than ionizing particles or gammas. The nuclear interaction [http://en.wikipedia.org/wiki/Cross_section_(physics) cross-section] is much more important here than dE/dx (ionization) energy loss. Materials rich in carbon and hydrogen (for example, paraffin) are far more effective at neutron shielding than dense metals like lead.(* for the expert readers) Yes, there is n-e scattering through W and Z exchange, but the cross-section and energy scales are completely irrelevant to this discussion.

So how do i do it? i'm kinda guessing i have to connect the input wire on parallel or in series with some batteries to the bulb so the high freq voltage or current would get up, and i also will put a potentiometer to get it to the stage before ionization so.... yeah thats all......thnx for all answers.

I think it would look fantastic, but would it work?

Watercooling a PC with a central heating radiator?

So I'm completely new to water cooling, I own a closed loop cooler and I know the names of the water cooling parts and assembly, but I have no real experience. I presume it's possible to use a normal radiator as a passive radiator in a loop, but I've got a couple of questions. First, do I have to be worried about what the radiator and waterblocks are made of, are the metals important? Second, will I need a significantly more powerful pump than the standard D5? Thanks! P.S. the rad I had in mind is this http://www.screwfix.com/p/flomasta-type-11-single-panel-single-convector-radiator-white-300-x-800mm/38602   It's rated for 1505 BTU/hour, which equates to 441W, which is in theory plenty my PC (4670K, HD7850 which I'll probably upgrade in the near future) The reason for using this kind of radiator is because they're far cheaper and passive, although I suppose the increase in pump power may negate quietness of no fans. It's also more fun ;)

insulating radiator cover

I'm looking for suggesting for upping the r-value on top of my radiator. Every window in my apartment has a radiator underneath it. I'd like to have some plants by those windows ('cause y'know, they need light and all) but I'm concerned about heat from below drying & killing the plants. A couple of the radiators have covers, but they're metal, so no insulation there. Ceramic pots may provide some insulation, but I'd really like to lay down a layer of some kind of building insulation proper just to be safe. The question is, what kind? Batting won't work, and the foam insulation panels I've seen at the hardware store I know are a fire hazard... plus not too fond of plastic-type materials. My dad suggested something he called "thermal block" which I believe is aerated concrete panels, but which I can't find a source to purchase. I'd like to spend less than $20, preferably less than $10 on this. Please help!
