ABSTRACT:
Apparatus for taking smear samples of the surface of objects for sampling radiation or chemical contamination levels. Both wiping area and pressure are controlled giving reliable, repeatable samples. A carriage provided with sampling strips is slideably mounted within a frame. Constant force springs pull the carriage across a known distance upon its release while a pressure roller on the carriage presses the sample strip to the area to be sampled. The sample strip is wound on a take-up reel as each sample is taken. The device is intended for remote or hazardous environments and may be operated manually or by robotics.
