By definition a lethal dose of x-rays would cause death.
Prior to death, the person would show signs of radiation poisoning including nausea, vomiting, hair loss, bloody vomiting (hemoptysis), bloody diarrhea (hematochezia), dizziness, low blood pressure (hypotension), slow wound healing, uncoordinated movement (ataxia), and seizures.
In practical purposes, a lethal dose of x-rays is nearly impossible since modern x-rays have such low levels of radiation.
For instance a single x-ray view of the chest is only 0.05mSv, which is the same amount of radiation you absorb from the ambient environment in 5 days. So, your risk of developing cancer, is only increased as much as it were to be if you were 5 days older than your real age.
For reference a lethal dose of radiation is approximately 30 Sv. So to get a lethal dose of radiation through x-rays you would need to get more than 600 x-rays in one sitting.
A lethal dose exposure of X-rays to the body can cause severe damage to cells and tissues, leading to symptoms such as nausea, vomiting, diarrhea, and loss of hair. In severe cases, it can result in organ failure, bone marrow suppression, and death.
Lethal dose means you die from it. hair falls out, gums start to bleed. internal organ failure. extreme cases, damage similar to heat burns.
Yes.
Some of the effects on the human body from a nuclear explosion are death (from thermal energy/blast effects or super lethal radiation exposure), infertility and blood disorders.
Yes.
Exposure to asbestos will likely compromise the immune system because of the long-term stress to the body. The test for asbestos exposure does not affect the immune system.
Your body can handle 10ppm (parts per million) for 8 hours. After that you are "hs2 saturated" and you body can't fight it a tenth as well. So to answer your question anything over 10ppm, or anything after 10ppm at 8 hours exposure.
Use as low-energy x-rays as possible. Don't get x-rayed unless it's actually needed. Cover parts not relevant to the x-ray with lead sheets.
The effects of radiation are dependent on the intensity and duration of exposure. See related links below for effects.
A fever, but not lethal.
Easy Lethal = Killer (mostly) Build = Body Put both together and you get "killer body". You know, like a boxer or a wrestler or a lifeguard. Muscular and toned.
LD50/30 radiation refers to the dose of radiation required to kill (LD=Lethal Dose) 50% of the test cohort within 30 days. Its normally specified for a particular species, rats, rabbits etc and is thought to be about 3-4 Sieverts in humans. The wikipedia article "Radiation Poisoning" has a table of effects of increasing radiation on humans. Note that at 3-4 Sv there are no skin effects if it is whole body exposure. If it is localised exposure then there will be radiation burns followed by erythema.
It does depend on the type of bacteria or viruses, the spectrum of body reactions to exposure to bacteria and viruses is very large, some of them are actually unimportant of even good for you, we all have colonies of bacteria in our body but they have no effect on our health, so the type of virus or bacteria is the key question
