Intensity of radiation is energy of the radiation emitted per unit time and unit area though unit solid angle.
Wavelength comes in if one is relating the intensity to the number of photons emitted rather than to thermodynamic variables.

All objects with a temperature above absolute zero (0 K, -273.15 oC) emit energy in the form of electromagnetic radiation. A blackbody is a theoretical or model body which absorbs all radiation falling on it, reflecting or transmitting none.
