Radium Chemical Company Carrier (ca. 1940 to 1960s)

This is a shielded carrier for brachytherapy sources. It was sold by the Radium Chemical Company, probably in the 1950s, but possibly earlier.

The company's catalogs that I have seen show something similar, except that the shielded potion of the illustrated carrier was a rectangular box rather than a cylindrical one like ours. These catalogs refer to it as an "Ernst Carrier."

An undated X-ray and Radium Industries Ltd. catalog includes a device that is almost identical to ours—they describe it as an "Operating Room Carrying Case."

A transport cart with rubber wheels was available from Radium Chemical Company for moving the carrier around.
