2014 NOHD calculations

A few people from the course asked if they could have a copy of the NOHD calculation that we carried out during the 2014 workshop.  For the lasers used at the workshop, the NOHDs extend well beyond the extent of the room.  For some, the NOHD exceeds the distance to the general public, 2 stories down (needless to say, we employ appropriate blinds over our windows!)

The excel file below contains the calculations and should automatically calculate NOHDs for you too, if you like.

Please do let me know if you plan to use this and acknowledge appropriately.  It has been peer reviewed, but there’s still likely to be a bug or two in the calculations.
