No of course not.
answ2. Light and heat are ordinary EM (electromagnetic) radiation.
Ionizing radiation is sufficiently energetic to remove parts of an atom, and to thus ionize it.
The UV from sunshine may damage the molecular bonds, but this is not ionizing radiation.
Some high energy photons in the UV range are ionizing radiations. The rest of the UV range, and visible and IR radiations are non-ionizing
The frequency range for visible light is 400-790 THz
Blue light is in the visible wavelength range.
Perhaps you mean one of these, I can't tell:Alpha particle radiation: least penetrating ionizing radiation, 100% shielding provided by one sheet of paper.ELF radio: lowest energy radio waves (~0.01Hz), travels long distances and through water. U.S. Navy experimented with it for communicating with Submarines.Red light: Lowest frequency of visible light.Violet light: Shortest wavelength of visible light.Very High Energy Gamma radiation: Shortest wavelength of any known radiation.Anyway, least in what way?
That would be visible light.
380nm to 750nm.
An X-ray (or Röntgen ray) is a form of electromagnetic radiation with a wavelength in the range of 10 to 0.01 nanometers, corresponding to frequencies in the range 30 PHz to 30 EHz. X-rays are primarily used for diagnostic radiography and crystallography. X-rays are a form of ionizing radiation and as such can be dangerous. In many languages it is called Röntgen radiation after one of the first investigators of the X-rays, Wilhelm Conrad Röntgen

Blue light is in the visible wavelength range.
Radiations within the range of 200 - 400nm are Visible Radiations. And others out of this range are invisible radiations.
That would be visible light.
380nm to 750nm.
The visible spectrum is one band within the full range of electromagnetic radiation.
The visible spectrum is the portion of the electromagnetic spectrum that is visible to (can be detected by) the human eye. Electromagnetic radiation in this range of wavelengths is called visible light or simply light.
