1.	Which one of the following is not a reason for not using X-rays in communication?(a) Highly attenuated(b) High power is required(c) Stopped by ionizing effects(d) Ionizing radiationI have been asked this question in an interview for internship.Question is taken from Electromagnetic Spectrum topic in division Introduction to Electronic Communication of Avionics
Answer» The correct ANSWER is (c) Stopped by ionizing effects Explanation: X-rays are not stopped by ionizing effects and that was the only reason they were ever thought they could be USED in communication. In re-entry vehicles, a temporary communication cut off is EXPERIENCED due to ionizing effects. X- rays were hard to modulate and focus and hence GRADUALLY let down.
