Tinkabel,
Yes, the PRC very KS one...
this is the first time I did the manual body check also, until 3 weeks ago I still walked through the machine. the micro-second to go through should be minimum harm. the detailed scan last week showed that bb is ok.
But hor, the lady officer press my tummy area quite hard leh, i think she is checking is its real tummy or plastic one filled with drugs. aiyo, even I dont dare to press so hard, later my bb get blue-black inside.
Actually the major radiation comes throughout the flight, especially during takeoff and landing where radiation is the strongests! some studies showed that it is even more than 10x the chest x-rays
