Environmental/Positron Shield
8 Interlocking Lead Rings Surround Chamber
Reduce background radiation more than 10 times with the environmental shield. Fitting any Capintec CRC dose calibrator with a remote ionization chamber, the shields consists of 8 interlocking lead rings that surround the chamber. Uniform wall thickness (4 cm standard, 6 cm upon request) also reduces radiation exposure during calibration. The lead contains 3% antimony for added strength. For use with CRC-15R, CRC-15W, CRC-127-R, CRC-712M, and CRC-15 beta.
