Economic evaluation for the design of a program for measurement of radon-222 concentration in housing in the city of Puno – 2024

Abstract

The importance of measuring the concentration of radon-222 makes it possible to assess the risk of exposure to this radioactive gas. The objective was to economically estimate the willingness of the inhabitants of the city of Puno to pay for health benefits for the prevention of cancer in the lungs of families and thus estimate the willingness to pay (DAP) using the contingent valuation method. A survey was carried out in 188 homes in the city of Puno. The contingent valuation method (CVM) allowed finding the economic valuation, this valuation was estimated using the Logit and probit model that by making a predictive capacity of the ROC curve and the area under the curve (AUC) obtaining values of (Logit: AUC = 0.8791; Probit: AUC = 0.8784) both give very good results, but with a marginal advantage for the Logit model, to carry out the design of a program to measure the concentration of radon-222 in the houses of the city of Puno. 64.89% of heads of household in the population stated that they were willing to pay S/ 24.76 soles for a single time per surveyed home. This indicates an amount that the family assigns to the benefit that the design of said program would generate. Its variables that influenced the decision were income level, education level, housing area, household size and sex, possible existence of radon-222 and location of the dwelling.
