Potrivit The Independent, exper\u0163ii NASA au dezv\u0103luit adev\u0103ratul pericol \u00een ceea ce prive\u015fte zborul cu avionul. Cu toate c\u0103 este cel mai sigur mod de transport, din punct de vedere statistic, trebuie s\u0103 \u015ftim c\u0103 atunci c\u00e2nd alegem s\u0103 c\u0103l\u0103torim cu avionul, ne putem expune la radia\u0163ii care, \u00een timp, ne pot afecta s\u0103n\u0103tatea.\u00a0 \u00a0 Zbur\u0103m aproape de limita superioar\u0103 a troposferei (stratul inferior al atmosferei), la 11.887 de\u00a0metri\u00a0\u00een\u0103l\u0163ime, astfel, spun exper\u0163ii NASA, intr\u0103m \u00een contact cu particule atomice cosmice ce pot fi d\u0103un\u0103toare. C\u00e2nd suntem la p\u0103m\u00e2nt, e mai pu\u0163in probabil s\u0103 intr\u0103m \u00een contact cu acestea datorit\u0103 c\u00e2mpului magnetic care \u00eenconjoar\u0103 planeta noastr\u0103. \u00a0 \u201eParticulele cu energie suficient\u0103, totu\u015fi, pot p\u0103trunde at\u00e2t \u00een magnetosfer\u0103, c\u00e2t \u015fi \u00een atmosfer\u0103, unde se ciocnesc cu molecule de azot \u015fi oxigen. Aceste coliziuni determin\u0103 particulele de energie \u00eenalt\u0103 s\u0103 se descompun\u0103 \u00een particule diferite prin procese cunoscute drept cascade nucleonice \u015fi electromagnetice. Dac\u0103 a\u0163i putea vedea particulele de la fereastra avionului, le-a\u0163i observa c\u0103 se str\u00e2ng \u00eentr-o regiune deasupra avionului. Densitatea atmosferei face ca dec\u0103derea s\u0103 se petreac\u0103 predominant la o \u00een\u0103l\u0163ime de 18.288 de metri de p\u0103m\u00e2nt ceea ce creeaz\u0103 un strat concentrat de particule de radia\u0163ii cunoscut sub numele de maximul Pfotzer. Ceea ce \u00eenseamn\u0103 c\u0103 membrii echipajului sunt clasifica\u0163i drept \u00ablucr\u0103tori expu\u0163i la radia\u0163ii\u00bb datorit\u0103 expunerii lor continue la razele cosmice\u201c, declar\u0103 exper\u0163ii NASA.<\/p>\n
