Final answer:
The statement suggesting gamma radiation from Co-60 has longer wavelengths than that from Ir-192 is false since both emit gamma rays with very short wavelengths, with gamma rays being more energetic and having greater penetrating power than visible light.
Step-by-step explanation:
True or False? Gamma radiation emitted by a radioisotope of Co-60 has wavelengths that are longer than the radiation from Ir-192. This statement is False. Gamma rays are a form of electromagnetic radiation with very short wavelengths. Cobalt-60 (Co-60) is known for emitting gamma rays with a very short wavelength, typically on the order of 10-12 meters, which is much shorter than visible light. Given the nature of gamma radiation.
it would not have wavelengths longer than those of iridium-192 (Ir-192) assuming both isotopes are emitting gamma rays. Gamma rays have a greater energy than visible light and have greater penetrating power through matter.
