DEPLOYMENT AND INSTALLATION

TS-100 aspirated radiation shields come partially pre-assembled and have few parts, facilitating easy

transport, deployment, and maintenance.

Avoid placing the shield near buildings, paved surfaces, or any other locations which may create a micro-

environment significantly different than ambient environment. The World Meteorological Organization

(WMO) recommends a mounting height of 1.25 to 2 meters above ground. Air temperature typically

decreases with increasing height above the ground surface.
