Even if you took him to get an x-ray the beads are plastic and would not show up. My son swallowed a penny and we called the doc they said as long as water could be swallowed then his throat was clear and it would pass in a couple of days and it did. Reading things on the internet is not always the best idea unless you can read it and not let it upset and just be aware of a POSSIBLE side effect not a DEFINITE one (which I can't, I'm like you it scares me everytime so I don't read things on the internet unless it is a site linked to my son's pediatrician's website). Calling his doctor is the best choice right now.
