Codes and Frequencies
For sample adults ages 18 and older who did anything to reduce the radon level in their homes (RADDONE), RADACTPLAN reports if the respondent, or anyone else, plans to do something to reduce the level of radon exposure in the home.
RADACTDK is included in the sample adult section within a series of questions about environmental health concerns, including testing for lead and radon. For more information and related variables, see RADHEAR or use the IPUMS NHIS search function and drop-down menus.
Changes in the universe affect frequencies for RADACTPLAN. In 1990 this question was asked of sample adults whose household was tested for radon and who did not do anything to reduce the radon level. In 1991, the question is instead asked of those sample adults whose tested radon level results were above the EPA guidelines of 4 picocuries per liter or whose tested radon level results were unknown. Additionally, in 1991, the response category "I did not think it was needed" was added. Researchers should use caution when making comparisons across samples.
- 1990: Sample persons age 18+ who ever heard of radon, whose household air was tested for radon, and who did not to anything to reduce the radon level (or for whom it was unknown whether they did anything to reduce the radon level).
- 1991: Sample persons age 18+ who have ever heard of radon, whose household air was tested for radon, and whose test results were above the the EPA guideline or were unknown.
