Radiation.........!?

According to bohr's postulates, radiation occurs if an electron jumps from an orbit E-2 to orbit of energy E-1.

then an energy, [E-2] - [ E-1] is released.

but, radiation is a nuclear phenomenon!

then, of these, which is right?

if both are right, then there are two types of radiation!

[one from inside nucleus and other from outside nuckleus]

What are the differences between these two?Radiation.........!?
Well, you are correct in that there are basically two things. There's particle emissions, such as alpha and beta radiation, and then there's pure energy radiation, such as gamma rays and light.



Electrons jumping around would generally be giving off electromagnetic radiation, such as light, x-rays, etc.Radiation.........!?
one is common and less dangerous and the other on is more deadly(I think)
