A black hole is invisible because its gravity is so strong that not even light can escape from it. This phenomenon is known as the event horizon, which marks the point of no return for anything crossing it.
Radiation strength refers to the amount of energy emitted by a radiation source per unit of time. It is a measure of the intensity or power of the radiation being emitted. The strength of radiation can vary depending on the type of radiation source and the distance from the source.
Yes, light bulbs emit radiation in the form of visible light.
An ionizing radiation is a radiation that is strong enough (energetic enough) to produce ions, that is, to separate electrons from an atom (thus leaving behind a charged atom, known as an ion)
No, you cannot be exposed to radiation from a person who just received radiation treatment. The radiation used in treatments like chemotherapy or radiotherapy does not linger on the person after treatment, so there is no risk of exposure to others.
Nuclear chemistry deals with the chemical reactions involving radioactive elements. Gamma radiation is due to the electromagnetic force, beta radiation is due to the weak nuclear force, and alpha radiation is due to the residual strong force (which you might call the strong nuclear force). So... if you didn't have the nuclear force, you wouldn't have alpha radiation.
at least as strong as a gorilla
it is strong
the weak and strong forces
well think =]

By invisible i assume you mean that the object does not emit electromagnetic radiation. In which case your answer is dark matter. Or potentially black holes (if you ignore the possibility of Hawking radiation).

It weakens the strength of it like diluting a drink so it doesn't taste too strong!
Hulk is strong because he was bombarded with radiation from a Gamma Bomb while trying to save Rick Jones.
There is a subtle difference. Background count rate is the measure of how strong the background radiation is.
i take it you go to stretford grammar ;P
