LOUISUSTUSSUULZUSTIO IURU Question 19 4 pts A researcher is interested in examining the association between radon exposure and development of lung cancer in Philadelphia He divided the entire population (population of Philadelphia) into 85 different groups based on zip codes. Then, out of 85 groups, researcher randomly selects 10 groups, including all the people in those groups. Researcher concluded that people w radon exposure areas had a 10% increased risk of developing lung cancer. People who live in moderate radon exposure areas has 20 % increased risk of developing lung cancer. People who had high radon exposure had 40% increase risk of developing lung cancer. The comparisons were made against people who live in radon free areas. 5. Can you list two potential confounders in the association between radon concentrations and lung cancer cases.

Answer 1

The two main confounders for radon concentration and lung cancer are:

1. Radon decays quite quickly giving away radioactive particles which are inhaled if some on is in exposure of radon. The long term exposures causes lung cancer as it causes damage to the cell lining in the lungs.

2. Radon is a inert gas which is naturally released from Radium. The  rocks,soil and groundwater are its sources of spread. It basically causes damage to the DNA of the epithelium of the cells of the respiratory system hence causing lung cancers.
