The study of high-energy, electromagnetic radiation, which includes x-rays, is called atomic spectroscopy.
The study of nuclear radioactivity and decay is called nuclear physics.
For the study of electromagnetic radiation of energies below x-rays you have:
UV - UV spectroscopy
Visible Light - gaffer
Infra-red - infrared spectroscopy
Microwave - microwave spectroscopy
Radio - amateur broadcaster
Radiology
mutagens
diversity among organisms
radioactive
no
nothing
Gamma rays are particularly energetic photons. On Earth, they are emitted from radioactive substances, during radioactive decay and are also created in x-Ray machines. They can also be produced during very energetic events in space, such as the explosion of a star. Cosmic Rays are gamma rays that continually bombard the Earth.
Both beta rays and gamma rays are the products of radioactive decay and are the result of changes in atomic nuclei. X-rays can be generated by using high voltage to accelerate electrons and slam them into a metal target, so they might be said to be non-radioactive.
The study of x-rays is radiology.
The study of x-rays
the branch of medical science dealing with the medical use of X-rays or other penetrating radiation. the use of radioactive substances in diagnosis and treatment; the use of radiation (including ionizing radiation, especially X-rays) in diagnosis, usually through the formation of images; radioscopy
yeah! almost all radioactive materials are dangerous, from these material radioactive rays are originated which are namely alpha,beta,gamma and when these rays strike to the body so it leave incurable burn,however its small amount is also harmful such as: the radioactive material named radium are found in varieties of wrist watches so its also harmful for human health X-Rays are electromagnetic rays and these are also harmful but not so much therefore physicians avoids for X-rays reports but in severe condition they are compel to do that advise There are two type of radioactive element one is natural radioactive and other is artificial radioactive element From natural radioactive element radioactive rays are always originated so,radioactive materials are dangerous even it is artificial or natural
Radiology is the medical term meaning the study of x-rays and other imaging studies.
