====== Radon Abatement Working Group ======

A conclusion of the March 2014 AARM meeting is that we should pursue detailed studies of radon plate-out and diffusion. Radon plate-out and diffusion are topics of interest to the greater low-background community. A great deal of work has been done in the study of radon plate-out and radon diffusion. Studies point to environmental factors playing a large role.

===== Meetings =====

We will use Big Blue Button.  Instructions below:
  - Go to the following website: http://shemp.physics.smu.edu/physics/index.jsp
  - Enter your name in the box 'Full Name'. This is how your name will be displayed for everyone to see.
  - Select 'Virtual Room - AARM Conference Room' from the pull down session menu.
  - Enter the pswd for the conference 'faarm'. Note it is case sensitive.
  - Hit the 'Join' button.
Once the session starts you will be prompted to 'allow' or 'deny' flash settings. You should select 'allow'. Then you will see a box to test your audio settings. If everything looks good hit 'Join Audio'.
