An integrating Rn daughter dosimeter using conventional Dy-doped CaSO/sub 4/ thermoluminescent (TL) material has been developed for use as a personal monitor. The dosimeter was found to have a linear response over the range 0.5 WL-h to 25 WL-h and to be insensitive to the state of equilibrium of the Rn daughters. The use of the dosimeter to monitor both /sup 222/Rn and /sup 220/Rn daughters is described. The limiting sensitivity of the dosimeter, at a sampling rate of 1 L min-1, was determined to be 0.1 WL-h for /sup 222/Rn daughters and 0.5 WL-h for /sup 220/Rn daughters. The application of the thermoluminescent dosimeter (TLD) to occupational monitoring of /sup 222/Rn and /sup 220/Rn daughters is discussed.
