Radioactive substances that emit positrons are used in scans?
PET scan
What range of electromagnetic radiation is used in NMR?
Molecules emit electromagnetic radiation in NMR spectroscopy.
How much radiation does MRI emit?
There is no ionising radiation (e.g. X-rays) used in an MRI scan. It utilises radio-waves and a strong magnetic field but no radiation.
Are gamma rays used in laser pointers?
no , laser pointers emit a lower wavelength of radiation
What kind of radiation do photocopy machines emit and what is the exact wavelength of this radiation on average?
Other than visible light used to scan the original to be copied, some heat, and the kind of very low and extremely low frequency electromagnetic radiation emitted by all electrical devices, photocopiers do not emit radiation.
What are the types of electromagnetic radiation commonly used to identify substances?
You could conceivably used any type of radiation to identify substances however the most commonly used ones are the Ultra-violet as they produce fluorescence in the visible range.
Why are radioactive pigments not used?
Radioactive pigments are not used because they emit radiation. It's unsafe, especially for children and pregnant women.

Radiation
What is a radiology report?
Radiology is used in specific with patients who use radiology treatment. One of the most common treatments in regards to radiology is cancer.
What is a radioisopes?
A radioisotope is a radioactive isotope. When radioisotopes decay, they spontaneously emit particles and radiation. Radioisotopes are commonly used in scientific research and medicine.
Why is the electromagnetic spectrum such as radio waves used to study space?
Most stars and many other objects in space emit radio and microwave radiation. Even the big bag emitted electromagnetic radiation.
