Understanding Neutron Radiography Post Exam Reading VIII-Part 2a of 2A

3. Pocket Chambers (indirect-reading) vs Pocket Dosimeters (direct
reading)
1. Pocket chambers were far less expensive (ca. $5 vs $40 in 1950)
2. Pocket chambers, despite their problems, were more reliable.
3. Pocket chambers did not permit the wearer to know their exposure, for
military purposes, this was sometimes desirable.
4. Pocket dosimeters allowed the worker to check their exposure during a
particular task and to take corrective actions when appropriate.
5. Pocket dosimeters did not have to be recharged every time they were read.
6. Pocket dosimeters could use very small chargers, small enough to easily
fit into a pocket.
