Prototype Hanford TLD Badge (ca. 1968) |
|
|
This was a test prototype for the "basic" Hanford TLD badge and it dates from approximately 1968. The plastic sleeve (with attached clip) contains a laminated white card marked "Dosimeter Test Sample" to serve as a substitute for the worker's ID card that would be used in a real badge. It also contains an orange plastic card that holds a LiF TLD chip sandwiched in Teflon. This badge might well represent the first time that LiF chips were mounted in Teflon in this fashion. |

The second circle, towards the bottom of the orange card hides a TLD-Teflon
disk which served as the backup dosimeter.
