- This is overly severe. The concept of ALARA (as low as reasonably

- This is unfortunate because it makes a mockery of radiation safety. It
- opates those who abstractly fear radiation but for those with some knowledge
- of radiological procedures, it is the radiation equivalent of crying
- wolf. Pretty soon the mockery destroys confidence in the system. People
- begin to assume that ALL radiological hygene procedures are "wolf crying"
- and ignore them.
