Here is a nice quote from the relevant wikipedia page:<p>&quot;However, other radiation authorities, including the International Atomic Energy Agency and Nuclear Energy Agency recommend against using ionizing radiation on certain populations like pregnant women and children&quot;<p><a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Full_body_scanner" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Full_body_scanner</a><p>So it just depends on who you think has authority. Presumably the people from the institute did in fact read a physics book at some point in their career.<p>It&#x27;s not your child. You get to decide for your children and he gets to decide for his. If we all had to go and study physics in order to decide whether or not a certain risk is worth taking or not the whole circus would grind to a halt. We&#x27;d all be making maximally informed decisions - once we finished studying. And even then, after studying that physics book he might conclude it still isn&#x27;t safe.
