[ RadSafe ] Best technique to detect DU in huge area!!!

[Abujarad]

Dear All 

Your advice is greatly appreciated:

There is a potential to perform Radiation survey in huge area 10 km x 30 km
or more for possible contamination with DU as a result of Gulf war.

 

The area is desert, sandy and not uniform.

 

What is the best technique to perform that?

Is movable FIDLER (NaI 2inx2in) with GPS and data timing is the best?

Any advice about the cost (individually and array as example 6 with trailer)

Suitable manufacturer and contact. for complete system..

Best regards
