Just the same as it means in every other context. The molecules/atoms are moving around due to energry created from waves of a source (sound, light, ect.)
Nuclear activity
ALARA stands for "As Low As Reasonably Achievable." It is a principle to minimize radiation exposure by keeping it as low as possible without sacrificing the benefits of the radiation source. ALARA is used to guide practices and regulations in industries and activities involving radioactivity to protect workers and the environment.
The answer depends on what substance carries the radioactivity because radioactivity is not a linear process.
This depends on the amount, specific activity, chemical form, type of emitted radiations.
In terms of radioactivity it is an alpha particle.
It is a non-absolute linear scale for the measurement of temperature or thermal activity.
emitting from radioactive elements which can cause fogging photographic plate is called radioactivity
What sources of radioactivity will result in water pollution
henri bacquerel discovered radioactivity in 1896.Artificial radioactivity was first discovered by Joliot Curie and her husband in 1934 while studying the effect of alpha particle bombardment on like elements like Aluminium
No. The activity rate declines exponentially but mathematically, even though it gets closer and closer to zero, it can never attain that value.
