Our eyes can detect radiation of wavelength ranging from 4000 Angstrom to 8000 Angstrom.
Radiation
Telescopes can not detect any radiation for which they were not specifically built. For example, a radio telescope is specifically designed to detect radio waves. Also, telescopes can not detect radiation that is too faint for them. What is too faint depends on the capabilities of the telescope.

Because the people whose eyes could not detect visible light didn't surviveto have children. They were completely outclassed, outhunted, and outfoughtby the people whose eyes could detect it.

The sunshine
We detect electromagnetic radiation in a narrow band of frequencies that we call "visible light" with our eyes. We can feel a broader spectrum of electromagnetic radiation that we call "heat". (There are some overlaps.) We can build tools that detect ANY frequency of electromagnetic radiation, and display that in any format we select.
Our bodies can detect the heat from infra-red light, and will convert some micro-waves directly into heat. Our eyes can (by definition) detect visible light. Our bodies do not detect any EM radiation more energetic than visible until after that radiation has done damage to our bodies. That's why we get a tan from UV light, burns from x-rays, and radiation poisoning from gamma rays.
Electromagnetic waves or radiation. "Light," however, generally refers to that portion of the EM spectrum that our eyes can detect.
The answer depends on what "IT" is and what sort of radiation it is meant to detect!
Compound eyes detect motion, and simple eyes detect light. or The compound eyes are used to "see". The simple eyes are used to detect light intensity.
Generally, photons are very easy to detect. Your eyes do a good job of detecting photons within a certain frequency band, as photons constitute light and other electromagnetic radiation. Individual photons are impossible to detect with modern technology.
none of your senses can detect radioactivity by themselves
