Background information about the required resolution:

Currently (2016) the French Enfants de la Lune association is using an
|
|
|
erythema-weighted meter calibrated in MED/hr, which is used as a survey
|
|
|
meter to determine the safety or otherwise of an environment. The
|
|
|
instrument display has a precision of 1 mMED/hr. If it does not read
|
|
|
zero (i.e., if the dose rate is greater than about 0.5 mMED/hr) they
|
|
|
consider it unacceptable. Now it is clearly questionable what dose is
|
|
|
clinically relevant, but as this intensity level is reasonably
|
|
|
achievable with window film and adapted lighting etc., they have
|
|
|
basically set their limit at the minimum detection level of their
|
|
|
instrument. So this is where our instantaneous sensitivity requirement
|
|
|
comes from.
