called radon.Ra-don is produced naturallybyuranium and radium deepinrocks below the surface ufthe soil.It makes its way upto the surface and entershomes through cracks in thebasement or around under-ground pipes.  \nRadon isn't dangerouswhen it is underground.Butonce in the air,it breaksdown into several radioac-tive substances.Radioactioesubstances are substancesthat give off harmful rays.Some of these substances,  \n# CURRENT EVENTS\n\nRodon enters houses through crocks and holes in the basement or first floor.Eachausts onappliances and drafts on sfovepipes tend to drow more

some people.  \nAlarmed Oficials  \nThe EPA has long knownthat high concentrations ofradonin the air are harmful.And it first told homeown-ers to test for radonin 1984.But a recent nationwidesample testing so alarmedEPA officials that they havecalled upon all Americansto test for radon as soon asthey can.  \nNearly one-third of thehomes tested by the EPAshowed levels of radonhigher than the EPA's rec-  \nommended danger level offour picocuries (pCi)of ra-don per liter of air.A pico-curie is one-trillionth of acurie,a standard measure ofradiation.  \nIf the testing represents,a true sámpling,and the EPAsays it does,more than 8million U.S.homes may con-tain enough radon to pose ahealth hazard.And morethan 200,000 homes mayhave extremely dangerouslevels of radon.  \nThe survey also indicatesthat radon in homes maycause as many as 20,000lung-cancer deaths a year,making it the second lead-ing cause of that form ofcancer after smoking.Mil-lions of Americans,says theEPA,are now at risk forradon-caused hung cancer.  \nSome states appear tohave more of a radon prob-  \nAn oxpert checks a house  \nlem than others.(See graphon p.4.)In Minnesota,forexample,over 46 percent ofthe homes surveyed hadmore than 4pCiof radon perliter ofair;in North Dakotathe figure was a nationalhigh of 63 percent.  \nHow To Test  \nFortinately,says the EPA,it's easy and inexpensive forhomeowners to test theirhomes for dangerous radonlevels.Hardware stores andeven supermarkets nowsellradon detectors,some for aslittle as $10.But,war er-perts,people should buy adetector that is EPA-ap-proved.If homeowners arenot sure which detectors areapproved,they can get a listof approved detectors bywriting or calling the EPA.  \nThere are two main means  \nContinued on Next Page  \nPEOPLE IN THE  \nnewS  \nCONTINUED FROM PAGE 1  \nof detecting radon levels inthe air,both of which in-volve placing a small collec-tor in the home for days ormonths and then sending thecollector toalab to measurethe radon buildup.But to becompletely safe,says theEPA,homeowners who usewell water should also testtheir water for radon buildup.Radon is removed from mostcity or town public watersupply systems.  \nCritics  \nhigh.  \nCritics have attacked theEPA decision from bothsides.Some complain thatthe EPA may have underes-timated the dangerfrom evena small amount of radon.These critics say thatbreathing even a reasonably“safe”4 pCi of radon for 18hours a day carries the samerisk of lung cancer as smok-ing half a pack of cigarettesdaily.  \nOthers,such as scientistWilliam Mills,argue thathigh radon levels
