The unshielded radiation survey was performed in the Cyclotron tank by the RH group using the service bridge, 
tool trolley, and radiation survey attachment on 2017-01-30 (see attached plot).

The shielded radiation survey was performed in the Cyclotron tank by the RH group using the service bridge, 
tool trolley, and radiation survey attachment on 2017-02-02 (see attached plot).

A obsolete version of the radiation survey procedure (from Don Jackson) that needs revising and the MATLAB code 
for generating a radiation survey map (from Maxim Kinakin) is attached.
