Fortunately there is case law where courts have ruled that meeting 
the regulatory limits determines that the individual was not exposed 
to any harmful dose of radiation, and was deemed not to be adversely 
affected. I say this is fortunate because if that were not the 
situation, then any court based on any legal proposition that ALARA 
was not met, would be difficult to judge, since as you pointed out, 
what is reasonable to one may not be reasonable to another. 

While the De Minimis rule was never promulgated, there are many 
instances of De Minimis in 10 CFR 20 for example. The 10% rule 
requiring monitoring is one. The 0.1 Rem public dose limit is another 
one. the 0.5 rem fetal dose limit is another one (which coincides 
with the 10% rule for required monitoring). 

ALARA is simply a bad philosophy considering that it really can't be 
defined due to the subjectiveness. If I use $10,000 per manrem as 
compared to another facility using $30,000 per manrem, which one of 
us is not ALARA? Since there is no definitive criteria, the 
reasonableness is assumed, and I say that both are. However I 
hypnotize that the facility spending the $30,000 per manrem saved is 
actually doing their employees, stakeholders and management a dis-
service, since they have spent considerably more money and show no 
real positive benefits, not have they really averted any significant 
adverse affects. Those who state they can justify really can not show 
positive causal relationship, nor benefit. It is all simply assumed 
to be. That doesn't make it so.
