ac·ti·va·tion

(ak'ti-vā'shŭn),
1. The act of rendering active.
2. An increase in the energy content of an atom or molecule, effected by means such as increased temperature or absorption of light photons that renders that atom or molecule more reactive.
3. Techniques of stimulating the brain by light, sound, electricity, or chemical agents, to elicit abnormal activity in the electroencephalogram.
4. Stimulation of peripheral nerve fibers to the point that action potentials are initiated.
5. Stimulation of cell division in an oocyte by fertilization or by artificial means.
6. The act of making radioactive.

Nuclear medicine Radioactivation. The interaction of a particle with an atomic nucleus, which “kicks” the nucleus into an unstable, high energy state, causing it to become radioactive.

Patient discussion about activation

Q. Are there any nice activities for adults with autism? I've been helping a very nice man of 45 of years old and I'm looking for some new things I can do with him in our time together. any ideas?

A. Autistic people react wonderfully with animals. for instance- i saw a group of severe Autistic teenagers going to swim with dolphins. the effect was amazing! taking him to the zoo, or even to the park to feed ducks, pet dogs, whatever.. could have a great effect on him.
hope i helped!
tell me how it went.

Q. what is a passive smoking? and is it dangerous as an active?

A. Passive smoking is the exposure to cigarettes smoke emitted from cigarettes smoke by other person. It's dangerous and may increase the risk to several diseases similar to active smoking (one's exposure to smoke emitted from the cigarettes he or she is smoking) although the risk is of lower magnitude. Example for passive smoking is children of smokers etc.
