I don't know if this is relevant or not but I'll ask the question anyway. Is there any relevance to ranking the risk of exposure, whether it's inhalation or ingestion? If you possibly have shrapnel in your body by fluke, is there any way of saying that this shrapnel or exposure by inhalation put you at higher risk? Has that been determined?
