IVCA FINAL EXAM - CHIROPRACTIC 2025 QUESTIONS WITH 100% PASSED ANSWERS!!
What is the EPA action level for Radon? - (answer)4 pCi/L
What is the risk of smokers and non-smokers getting lung cancer from Radon? - (answer)62/1000
smokers
7/1000 non smokers
What determines the risk of getting lung cancer from Radon? - (answer)Concentration of Radon and
RDPs and Length of Exposure
Hoe does Radon enter the home? - (answer)Radon gas moves through the ground due to air pressure
differentials in the home, and up into the home through cracks or other openings in the foundation. Can
also enter through well water and some building materials.
How is radon formed? - (answer)Decay of Uranium-238 into Radium-226 with the release of alpha
particles, followed by the decay of Radium-226 into Rn-222 with the release of alpha particles
How do we know about the effects of Radon? - (answer)Epidemiological studies were completed on lung
cancers in workers, especially miners.
What are the 4 RDPs that Radon decays into? - (answer)Polonium-218
Lead-214
Bismuth-214
Polonium-214
What is the most common form of a radon mitigation system? - (answer)Active Soil Depressurization
(ASD)
True or False - Radon levels are the same in each house. - (answer)False
, IVCA FINAL EXAM - CHIROPRACTIC 2025 QUESTIONS WITH 100% PASSED ANSWERS!!
Why are radon concentrations higher in the winter? - (answer)Houses are in closed conditions, which
increases Radon concentrations
Which RDP(s) damage the lungs? - (answer)Polonium-214 and Polonium-218
True or False - There are no health risks if Radon concentrations are below 4 pCi/L. - (answer)False
What is the OSHA Occupational Radon Exposure Level for adults in a 40 hour work week? - (answer)100
pCi/L or 12 WLM/Year RDP cumulative exposure for 1 working year
What are the requirements before conducting a short-term radon test? - (answer)1. Closed building
conditions for at least 12 hours prior
2. Indoor temperature must be 65-80°F
*Requirements and testing protocol must be told to homeowner prior to starting the test when possible
*May want a non-interference agreement with homeowner
*Request posting "Radon Test in Progress"
How long can a short-term radon test be deployed? - (answer)46 hours-90 days, optimal time is 48
hours
What is the purpose of a short-term radon test? - (answer)Quickly identify a potential radon hazard
What is simultaneous short-term testing? - (answer)Running two tests at the same time, average the
results to determine if mitigation is required
What is sequential short-term testing? - (answer)1. Conduct a single short-term radon test
- If 4 pCi/L or higher, retest right away using a short term test and then average both results to make a
mitigation decision.
- If between 4-7.9 pCi/L a short or long-term test may be used for the second test, then average both
results to make a mitigation decision.
