For a substance to be radioactive, it has to emit radiation.Radiation is defined as energy emissions, often as electromagneticwaves or subatomic particles.
some atoms have a center that isn't stable. This center sometime looses parts, like a proton or a neutron. That part is released with an enormous amount of power. We call that… a radio active rays. A not stable atom is a radio active element. That together is radio activity. (MORE)
Yes. A radioactive atom is a radioactive atom. If that atom exists as a single atom and is uncombined and it is radioactive, it's radioactive. If that same atom is chemically …combined with another or other atoms, it's still radioactive. It's just that simple. (MORE)
Yes. A radioactive standard is a configuration of radioactive material constructed in a precise way, allowing the standard to be used as a reference when measuring other radia…tion sources. Standards typically come as solids trapped in a mylar foil pocket, embedded directly in a plastic or electroplated onto a metal disc, or as a sealed liquid solution. Standards are used to calibrate radiation measuring equipment. (MORE)
It depends. There are over 20 isotopes (types) of copper. Most of them are radioactive, but also quite rare. So any copper an average person would see would not be radioacti…ve. (MORE)
Radioactivity is the process of process of spontaneous disintegration of nucleus and is measured by Geiger counter. It remains unaffected by external factors like temperatures…, pressure etc. It involves emission of alpha, beta and gamma particles/rays. (MORE)
Radioactive decay occurs in unstable atomic nuclei - that is, ones that don't have enough binding energy to hold the nucleus together due to an excess of either protons or neu…trons. (MORE)
Radioactivity is the general property common to all radioactive materials. Radioactive is a qualifier used to identify materials having this general property. Example…s: .
The radioactivity of the sample was unusually high. .
Radioactive Carbon-14 levels in charcoal or bone can be used to determine age. (MORE)
Radioactivity was discovered by Henry Becquerel but the term 'Radioactivity' was given by Madam Curie. It is the process of process of spontaneous disintegration of nucleus an…d is measured by Geiger counter. (MORE)
