People always speak about radiation as if they know what it is. Some websites explain radiation as ionizing particles that contain enough energy to liberate an electron. What exactly is radiation besides claim of energetic particles and can there be proof?

Answer 1

Answer 2

There are two kinds of radiation.



1. Energetic particles, emitted from unstable atoms, called radioactive atoms. People develop all sorts of device to detect this. Geiger-Muller counter is one example. Another example is the screen used by Rutherford in his experiment. He shot alpha particles (emitted from the radioactive process of alpha decay) at a gold foil and found that it scattered to all kinds of directions. He used a screen around the device to detect which way the alpha particle went. Of course you cannot see the particles. But its effect is clear (exposure to radiation causes mutation, e.g., victims of the Chernobyl nuclear reactor explosion).



2. Electromagnetic waves are also called radiation. Examples include phone signal, radio wave, sun light, gamma rays (emitted by radioactive atoms), X-ray, etc. This is also dangerous at high intensity.

Answer 3

additionally inspect the CDC website below. Thyroid maximum cancers has a extreme therapy fee by using Iodine 131 radiation therapy. Thyroid cells are the sole human cells that entice iodine. So the radiation is introduced good to the thyroid or thyroid maximum cancers cells everywhere interior the physique and destroys them. The sufferers sweat and ex creations eliminate extremely some the radioactive iodine so for 3 days would desire to stay some feet removed from others. medical workers who paintings with nuclear medicine would desire to take greater suitable risk-free practices (in all hazard no longer lead gown yet a yellow danger gown) by using frequency of attainable exposures. I 131 (or radiation in maximum circumstances) would nicely be risky to healthful human beings (e.g harm your thyroid) so the precautions are taken. The worst area of the therapy is the weeks that the affected person won't be able to take their hormone drugs so that they are sluggish, drained, and torpid till they might start up the hormone drugs returned.

Answer 4

No definitive definition. Balogny.

Answer 5

All I know is that too much exposure to it and you could get cancer.
