MJ:
Ignore ~~Sheila. You know how it is in a classroom when the lesson is WAY over some of the kids heads and they "act out" their frustrations.
You are correct. A spectroradiometer is used to "calculate" the "te (time to 4.0 MED) time" of a sunbed and that determines the MTI (maximum timer interval) that is posted on it. The MAD (maximum allowable dose) is calculated (today) by multiplying 4.0 MED times the current "dose definition" of 156 J/m2. Thus, the MAD today is 624 J/m2 (4 X 156 J/m2).
If and when we go to SED, we will determine time to 8.0 SED.
The protocol we are now using at the UVR Research Institute calculates both (1) time to 4.0 MED and (2) time to 8.0 SED.
You get two gold stars on your forehead! (~~Sheila gets another black star - LOL - but think how great a gold star, when and if she gets one, will look on top of her black ones!)
