Radiation is a natural part of our environment.
In fact, everyone has a small percentage of radioactive hydrogen and radioactive carbon in their bodies, and the air you breathe has a small amount of radioactive radon gas in it. You also receive some radiation from the sun.
So a little radioactivity (often termed as background radiation) is normal.
X-rays, fluoroscopy, and CT scans give a person small doses of radiation, but usually it is believed that the benefits outweigh the risks.
Radioactive decays can damage genes. However, the cells in your body have complex mechanisms to repair damaged genes. Unfortunately, not all damaged genes and gene transcription errors are fixed, and these errors can lead to cancer.
Ironically while radiation can cause cancer, it is also a common treatment for cancer due to its ability to kill rapidly dividing cells.
There are multiple theories about small does of radiation. Some theories suggest that any amount of radiation is harmful and increases cancer risk. However, there are many studies about an effect called hormesis in which low doses of radiation actually activate the immune system and have a beneficial effect.
High doses of radiation, however, can be very damaging and can be lethal. See the wikipedia article on radiation linked below. An acute dose of 300 to 400 REM is considered 50% lethal. An acute dose of over 1000 REM is considered 100% lethal. However, the radiation poisoning and death can occur over several days post-exposure.
What else can I help you with?
Can infrared radiation kill you?
Yes. At a high enough intensity any form of radiation can be deadly. All forms of electromagnetic radiation carry energy, which can heat objects. Intense enough infrared radiation can essentially broil you.
How long does radiation take to kill a human being?
The time it takes for radiation to kill a human being depends on the level of radiation exposure. High doses of radiation can cause death within days or weeks, while lower doses may take longer to show fatal effects, such as months to years. The specific type of radiation and the individual's overall health can also impact the time it takes for radiation to be lethal.
How long does it take gamma waves to kill you?
Gamma waves are a type of electromagnetic radiation, not harmful by themselves. However, exposure to extremely high levels of gamma radiation, such as from a nuclear explosion or certain medical treatments, can cause severe radiation sickness and potentially lead to death within days or weeks. The time it takes for gamma radiation to kill you depends on the intensity and duration of exposure.
What type of electromagnetic waves can be used to kill cancer?
Ionizing radiation, such as X-rays and gamma rays, are used in radiation therapy to kill cancer cells. These high-energy electromagnetic waves can damage the DNA within cancer cells, preventing them from dividing and growing.
How does nuclear power kill you?
Nuclear power itself does not kill you unless there is a steam explosion like at Chernobyl. It is the radiation either from fission products or direct neutron bombardment which will do that, and the effects of excessive radiation are well known and documented.
Will you die in radiation?
Yes, an overdosage of Radiation can kill you.
Good things about radiation?
Chemo radiation kill cancer cells.
Did cosmic radiation kill the dinosaurs?
no
Would radiation kill you?
yes
Would 150 radiation kill you?
No
Can death rays exist?
It depends... Radiation can kill a man easily, but to form a hand held "ray" that emits enough radiation to kill? No.
What can a person do to kill cancer?
Chemothrapy and radiation
Can radiation kill people?
Yes. It is extremely hazardous.
What is the use of beta radiation?
to kill cells in an an organ
Why do you need some ultraviolet radiation?
Ultraviolet radiation can kill some microorganisms and has a role in the vitamin A synthesis.
How does a atom bomb kill people?
Due to Big Explosion and has a Radiation which can kill many lives...
What are the disadvantages and advantages of gamma-ray?
Gamma rays are the highest forms of electromagnetic radiation. They are a type of ionizing radiation, and they can damage tissue. This can lead to radiation sickness or, in sufficient doses, it can kill. --------------------------------------------------------------- Gamma Rays are able to kill living cells so it's used as medicine to kill cancerous cells. If there's an overdose though, it could kill you. It is a hazardous radiation so if you're not specialized in it, then DO NOT mess with Gamma Rays because again, too much could kill you.
