Shielding (Radiation)

Published: Oct 15, 2018

Shielding is a major protection principle for reducing exposure to Ionising Radiation (the two other related principles being Time and Distance). See Lead for a shielding example.

The definition of 'safe' is not strictly an engineering term; it's a societal term. Does it mean absolutely no loss of life? Does it mean absolutely no contamination with radiation? What exactly does 'safe' mean?
