Experiment comparing twins (one urban, one rural) ability to clear airborne radioactive particles from their lungs
A dataset with 14 observations on the following 3 variables.
Pair |
Code for the twin pair: A - G |
Environ |
Living environment: Rural or Urban |
Percent |
Percentage of radioactivity remaining in lungs |
This dataset is from a study to compare the effect of living environment (rural or urban) on human lung function, where the researchers were able to locate seven pairs of twins with one twin in each pair living in the country, the other in a city. To measure lung function, twins inhaled an aerosol of radioactive Teflon particles. By measuring the level of radioactivity immediately and then again after an hour, the scientists could measure the rate of ``tracheobronchial clearance." The percentage of radioactivity remaining in the lungs after an hour told how quickly subjects' lungs cleared the inhaled particles.
This dataset was renamed as RadioactiveTwins for the second edition.
