X-ray Transmission through Shielding Materials

Some useful resource for broad bream transmission of x-rays through concrete (2.4 density) and lead ( 11 density). Please note the total bream filtration data. As noted before, this is for historical interest to physicists and Radiation Protection Advisers (RPA). In some cases this radiological data is over 50 years old. If in doubt please seek professional advice.

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?
