Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Kupfuura: Kenza yemapapu yakanga isingawanzowaniki kusati kwatanga kusvuta fodya; haina kutozivikanwa sechirwere chakasiyana kutozosvikira muna 1761. Mativi akasiyana-siyana ekenza yemapapu akarondedzerwazve muna 1810. Zvirwere zvomupapu zvine ngozi zvaingova 1% chete yemakenza ose akaonekwa pakuongorora zvitunha muna 1878, asi zvakanga zvawedzera kusvika ku10<unk>15% pakuvamba kwema1900. Mishumo yezviitiko muzvinyorwa zvokurapa yakasvika 374 bedzi munyika yose muna 1912, asi kunzvera kuongorora zvitunha kwakaratidza kuti kuwanda kwekenza yemapapu kwakanga kwakawedzera kubva pa0,3% muna 1852 kusvika pa5,66% muna 1952. MuGermany muna 1929, chiremba Fritz Lickint akaziva kubatana kuri pakati pokusvuta nekenza yemapapu, uko kwakatungamirira kumushandirapamwe une simba wokurwisa kusvuta. The British Doctors' Study, yakabudiswa muma1950, yakanga iri ufakazi hwekutanga hwakasimba hweepidemiological hwechisungo pakati pekenza yemapapu nokusvuta. Somuuyo, muna 1964 Chiremba Mukuru weUnited States akakurudzira vasvuti kurega kusvuta. Kubatanidzwa negasi raRadon kwakatanga kuzivikanwa pakati pavashandi vomumigodhi muOre Mountains pedyo neSchneeberg, Saxony. Sirivha yave ichicherwa ikoko chifo cha 1470, uye iyi migodhi yakapfuma muuranium, negasi rayo rinoperekedza rinonzi radium neredhoni. Vashandi vomumigodhi vakava nezvirwere zvemapapu zvakawanda zvisingaenzaniswi, zvakazozivikanwa kuti kenza yemapapu muma1870. Pasinei nokuwanwa uku, kuchera kwakaramba kuchiitwa kusvikira kuma1950, nemhaka yokudiwa kweuranium neUSSR. Radon yakasimbiswa sechikonzero chekenza yemapapu muma1960. Kurapa nemwaranzi kunoderedza marwadzo kwave kuchishandiswa kubvira muma1940. Kurapa nemwaranzi kwakanga kwatanga kushandiswa kuma1950, kwaiva kuedza kushandisa mwaranzi yakawanda kuvarwere vaiva nekenza yemapapu yakanga ichangotanga, asi vakanga vasingakwanisi kuvhiyiwa. Muna 1997, CHART yakaonekwa senzira yokuvandudza kurapa nemwaranzi kunoshandiswa mazuva ano. Nokuda kweSCLC, kuedza kwokutanga muma1960 pakuvhiya uye kurapa nemwaranzi kwakanga kusina kubudirira. Mumakore okuma1970, mishonga yokurapa nemakemikari yakabudirira yakagadzirwa.  Mubvunzo: Kuchinja kupi kwakawedzera kuwanda kwekenza yemapapu?
