Yes, most of the radiation used during X-rays is quickly absorbed by the body's tissues or shielded by lead aprons. Any remaining radiation is typically very low and decreases rapidly as the body eliminates it. Your body does not retain radiation from routine X-rays after the procedure is completed.
Yes, X-rays involve radiation in the form of electromagnetic waves that can pass through the body to create images of internal structures. However, the level of radiation exposure from X-rays is considered safe when used in medical imaging with appropriate protocols and precautions in place.
A black body emits more radiation than a white body. A black body absorbs all radiation that falls on it and re-emits it as thermal radiation, making it an ideal emitter. On the other hand, a white body reflects most radiation and thus emits less overall.
There is no strict limit to the number of X-rays that are safe at one time, as it depends on the specific circumstances and body parts being imaged. However, it is always best to limit exposure to radiation as much as possible to reduce health risks. Healthcare professionals will weigh the benefits of obtaining diagnostic information from X-rays against the potential risks of radiation exposure.
Heat can leave the body through several mechanisms, including radiation, conduction, convection, and evaporation. Radiation is the primary way in which heat is emitted from the body, as infrared radiation escapes through the skin. Conduction transfers heat to cooler objects in direct contact with the body, while convection involves heat being carried away by air or water currents. Finally, evaporation helps cool the body by converting sweat into water vapor, carrying away heat in the process.
Loss of infrared energy from the body is called thermal radiation.
Xrays and CT scans

because it enables you to see if you have a broken bone or not. however, it is dangerous as its bad for you, as the radiation waves get passed through your body and damage your insides! :) x
Xrays pass through most substinces. Various detectors can be used to detect the ammount of xrays that are sent from one side verses what is picked up on the other side. The difference can give you information about an object. Xray radiation is created when high speed electrons hit a solid object. Basically high voltage electricity (usually 40,000 - 120,00 volts) is pushed across a gap from a cathode to an anode. The Anode is usually made of tungsten or other materials that can withstand high temperatures. The anode is usually spinning so that the target is not hit in the same spot over and over again, this allows the anode to last longer. When the high voltage hits the target it releases xray radiation. Xray radiation is invisible, but it causes some elements to glow. The best used today are rare earth elements like yttrium and gadolinium. The xrays travel through the patient's body and hit a film cassette that is treated with some of these rare earth elements and it glows wherever the xrays reach it. Some of your body blocks the xrays so the screen only glows in areas that is not entirely blocked. The thicker and more dense the body part the more xrays are blocked. Bone is very dense so it blocks more xrays than most any other tissue, so bones show up as clear areas on the film. The film is placed between these screens inside the cassette safe from regular light. So that the only light that reaches this film is the light created by the glowing elements bombarded by xray radiation. The glowing of the elements bombarded by xrays causes the film to turn black and or grey depending on the amount of xrays that are blocked. Modern xray machines have cassettes that use different phosphorus materials that keep a temporary image on the cassette then the cassette is read by a machine and creates a digital image. There is no film in these type of cassettes. This is done because more and more facilities are not using film anymore. Storing xrays is cheaper and more efficient on computer hard drives as digital xrays. Because of the digital storage of xrays some xray machines do not use cassettes at all, only digital readers.
yes it is called having 'wet dreams'
Yes, there are several diseases that are treated with radiation, including some types of cancer. Radiation is also used in many diagnostic imaging machines, so that we can see inside the body without having to cut into it.
X-ray machines use electromagnetic radiation to pass through the body. Dense materials like bones absorb more radiation, appearing white on the x-ray image, while soft tissues allow more radiation to pass through, appearing as shades of grey. This contrast allows bones to be clearly visible on the x-ray image.
A spiral CT is a new technology, it refers to the way the xrays are emitted. The tube that produces the xrays is paralell with a receiver on the opposite side of the opening in the CT machine. To take the image, the tube and receiver are circling as it is doing this the bed is moving into the opening. This combination creates a spiral movement around your body. This new technology allows for a quicker scan and reduced radiation dose while not sacrificing the image quality.

No it can not.
