How does radiation work?
439626
Most of the naturally occuring stuff comes from unstable atoms.  When the balance between protrons and neutrons is out of whack, the atom will fly apart.  Depending on the atom, it will break apart in one of 3 ways, it will emit an electron (beta decay), part of the nucleus (alpha) or throw off an electromagnetic wave (gamma). \nGamma also commonly comes from high energy particle hitting the atmosphere and shattering atoms.  The interaction releases a shower of other particles some of which release gamma.  It's nothing to worry about as we evolved under these conditions and our bodies are build to handle it.

it absorbs light energy aka the photons and bounces them around and releases electrons

for radiation - how about someone sitting under the sun? Radiant energy is what heats you from the sun.\n\nFor convection (you seem to change your mind if you want convection or conduction info) you could think in terms of how a convector heater works - the warm air circulating the heat around the room. Convection also applies to liquids too - think of the water in the kettle and the water currents inside making all of the water heat more-or less together.\n\nFor conduction, how about a saucepan sitting on top of a cookers' hotplate?\n\nHeating by radiation is through infrared heat - from the sun, from a light bulb - even a bonfire but that can also be from convection too. Think in terms of "heatwaves" with radiation perhaps.\n\nConduction of heat is when two surfaces of dissimilar temperature are brough together. Some of the heat will travel by conduction (touching) to the cooler object.

E=MC2 doesn't talk about radiation.  It is about energy.  Nuclear bombs and nuclear reactors work off of the same principle.  Just in nuclear reactors, the reaction is controlled and made safe, and in bombs, the energy is released all at once.  When an atom is "split", the total mass of the origional atom and the neutron that splits it is more than the pieces that it breaks into.  That difference becomes heat energy, and the E=MC2 tells you how much energy.  The radiation that everyone associates with it comes before and after the nuclear reaction, when the nuclear fuel and daughter products (the pieces the atom split into) decay and emit various forms of radiation, depending on what is decaying.  E=MC2 doesn't talk about this part of the process, just about the moment the atom actually splits.  To reverse the process and convert energy into mass is mainly theoretical, though it is possible.  Lab conditions have achieved microscopicly small results.  This is the process that the transporters and replicators use on Star Trek.

I could not understand what did you mean by 'as such'! But, gamma rays are also photons and if certain conditions (conservation theorems, energy requirements) are satisfied, they could undergo the process of pair-production whereby they could be converted into electron-positron pairs (an experimentally observed fact).\n \nPair-production occurs when a 1.022 MeV gamma-photon interacts with a heavy atomic nucleus, and produces an electron and a positron without violating conservation of momentum. Pair production cannot occur in empty space out of a single photon because the momentum of the initial photon must be absorbed by something, and the heavy nucleus is thus required to conserve both momentum and energy. The energy of the photon 1.022 MeV, as described above, is the total energy of twice the electron mass (according to E = mc^2). Indeed energy is being converted into mass in this process!

first of all lets define radiation.\nradiation is the emission of waves or wave travel.\na wave comprises of wave lenths\n1 wave lenth is 1 crest and 1 trough\nwhat are the different types of waves\nthere are two main types\nfirst is the non-ionizing radiation or harmless\nand second is the ionizing radiation or harmful\nplease refer to an electromagnetic spectrum in where it is indicated in detail\nfrom non-ionizing:\nlong waves, radio waves,microwaves, infra-red, visible/white light\n to ionizing:\nUV, x-rays and gamma rays.\nThree main types of ionizing radiation\n1. alpha rays - highly ionizing weakly penetrating\n2. beta rays - med ionizing med penetrating\n3. gamma rays/x-rays - highly penetrating weakly ionizing\n\nso radiation from a blast could be light, and heat but if you use a nuclear bomb there will be ionizing radiation that will affect people and living things.\n\nthe difference between a bomb and a nuclear bomb or dirty bomb is that inside a bomb there are/is radioactive sources like Po, U, Fe and other radioactive sources.\n\nhow does it harm us. you cannot feel ionizing radiation. no human senses can detect them. only specialized equipment do like a geiger counter. ionizing radiation can alter DNA. so if you are affected by large dose, some of your cells will die and alter your DNA.\n\nprotect..?\n\nby using the Time Distance and Shielding concept\nless time you are expose less effect on your body\nradiation reduces its effect by 1/4 every 1 meter\nyou can shield yourself to radiation by knowing what radiatioactive source you are being exposed.\nalpha ray can be blocked by our own dead layer of the skin or paper\nbeta could be blocked by much denser material like book, water, aluminum, glass\ngamma could be blocked by a thick concrete or lead\n\nPM is you have more question

The current use of electromagnetic radiation to treat brain tumors are gamma rays not x-rays.  gamma rays are smaller and even more energetic.  Doctors are using these rays like a knife without ever opening the skull.  They use very small amounts of gamma rays that converge on one place in the skull in order to kill the cells in just that location.  It is amazing that it is an outpatient procedure but the risk of not "getting it all" increases.

The main difference between x ray and Gamma ray is that X rays originate from the electron transitions in the atom out side the nucleolus. But Gamma rays are emitted from the nucleus. \n\nX ray\nWavelength : 10 - 0.1 Angstroms (1 Angstroms = 10^-10m)\nX rays are high frequency electromagnetic rays which are produced when the electrons are suddenly decelerated - these rays are called bremsstrahlung radiation, or "braking radiation". X-rays are also produced when electrons make transitions between lower atomic energy levels in heavy elements. X-rays produced in this way have definite energies just like other line spectra from atomic electrons. They are called characteristic x-rays since they have energies determined by the atomic energy levels.\n\nWithin a short time of their discovery, they were being used in medical facilities to image broken bones. Also they are used to study the crystal structures.\n\nGamma Ray\nWavelength :  <0.1 Angstroms\nThe term gamma ray is used to denote electromagnetic radiation from the nucleus as a part of a radioactive process. The energy of nuclear radiation is extremely high because such radiation is born in the intense conflict between the nuclear strong force and the electromagnetic force, the two strongest basic forces. The gamma ray photon may in fact be identical to an x-ray, since both are electromagnetic rays; the terms x-ray and gamma rays are statements about origin rather than implying different kinds of radiation. Also they are produced from the positron-electron annihilation in presence of a nucleus.\nUsed in the gamma ray spectrometry.\n\nGamma ray autoradiography etc.\n\ni think your doubt has been clear.

what is the atom made of and explain how they work?

As you already know, X-rays are highly penetrating and the photons have very high energies, especially in your scenario.  When the X-rays collide with the skin molecules, they can tear these molecules apart.  Deeper within the body, the same process will occur with the internal organs, as these molecules are ripped apart as well. As you already know, X-ray radiation is used to treat cancer by targeting and destroying the cancer cells within the body.\nAs these molecules in these cells are ripped apart (destroyed), the cells will fill with fluid (edema).  Starting with the skin cells and moving within the body as well, great amounts of swelling will occur. As the edema overtakes the body, for example, a full body exposure, the victim will die when his/her lungs become filled with fluid.  This will also effect the pericardium around the heart, as well as the kidneys.  All of the these organs will eventually fail over a 48 hour period.  It could occur sooner depending on the individual.  But is is gruesome to watch and the victim is in horrible pain through the ordeal.

IR ray is an electromagnetic wave, like visible light, X-ray, gamma ray and UV ray(even radio waves). the energy of IR wave is lower than visible, UV, X-ray and gamma. when one of the high energy electromagnetic waves hit a molecular, they will brake it to smaller parts( if they have enough energy) but IR doesn't have enough energy, so all it can do is to make the molecules move faster. the movement average of molecules is what we call heat, so when IR hits a material, it'll rise the average molecular movement in it and we say that the material became hotter.

Electromagnetic radiation is a propagating wave in space with electric and magnetic components. These components oscillate at right angles to each other and to the direction of propagation.\n\nThe term electromagnetic radiation is also used as a synonym for electromagnetic waves in general, even if they are not radiating or travelling in free space. This sense includes, for example, light travelling through an optical fiber, or electrical energy travelling within a coaxial cable.\n\nElectromagnetic (EM) radiation carries energy and momentum which may be imparted when it interacts with matter.

Light is a form of atomic radiation.  When an electron drops to a lower shell it releases a photon.  \n\nOther radiation can stimuate the energy in atoms and cause electrons to bounce up and down levels creating photons as well.

No, only charged particles radiate photons when moving through a medium with a speed larger than the lightspeed of that medium. \n\nNeutron detection can be done with scintillator counters. What is detected is the signal of recoiling protons in the material, hit by the neutron.

Cerenkov radiation is 'braking radiation.' It happens when particle are travelling faster the speed of light in some medium. The energetic particles slam into atoms in the medium and slow down abruptly. As you may be aware, when you accelerate a charge, it radiates energy. This is no exception -- the particle radiates light, called Cerenkov radiation.

One way it actually interacts is by catalysing chemical reactions-various spectrums of light increase atomic bonding between different chemicals and atoms. Of course there is heat, the solar radiation excites atoms and increases their activity, generating heat. Most everything else is optics, like things we say as white reflect almost all the light hitting them and things we see as black absorb the entire spectrum of visible light.
