Landsverk Model L-50 Finger Chamber (ca. 1950 - 1955)

Manufactured by the Landsverk Electrometer Company of Cincinnati , Ohio .

This indirect reading dosimeter was designed to measure the hand exposures (in the 0 – 2 R range) of workers handling gamma ray or x-ray sources.  If desired, it could be attached to a clip or chain rather than a ring. For some odd reason (most likely it was a mistake),  Landsverk also used the Model L-50 designation for a direct reading pocket dosimeter.

Size: 1 9/16” x  0.5”

Weight: 0.2 oz.

Response: independent of energy from 75 keV to 1.5 MeV.

Charger/Reader: Landsverk Model L-60
