Can human senses detect radioactivity?
Yes. Radiation is just a way of describing how a photon travels. Radiation comes in many forms (i.e. frequencies). You can detect heat (radiation), light (radiation). You CANNOT detect, AM/FM radio waves, UV Light, X rays, gamma rays, cosmic rays. Most people consider “radiation” to be gamma rays, or beta and alpha particles that are emitted from a radioactive isotope (like some isotopes of Uranium and Plutonium).
