食物中點可知道有錪、銫等含輻射物質?

第一
所有核輻射都係無色無味無臭，憑肉眼絕對係睇唔到
所以如果想喺日常生活以自己既器官黎自我探測輻射，基本上係冇可能既事

第二
呢D放射性碘、放射性銫既化學特性亦都係同佢地各自既非放射性同位素(喺呢度即係非放射性碘同非放射性銫)
所以亦都唔使諗住可以用化學方法搵放射性碘同放射性銫出黎

仲有基本上你係冇乜可能買到/食到有輻射污染既食物
若然你真係買到畀輻射污染既食物
到你搵到探測輻射既方法，例如輻射計既時候，你既身體已經接收左一定劑量既輻射

我諗你都係信下政府對於進口食物既把關工作，好過真係膽粗粗自己去測試

You must not perform the tests by yourself because the contaminated food will hurt your health immediately so let the special goverment department to check them before you get near them . Radiation in food requires a multi-channel analyzers & a special oven for ashing the food to concentrate the radiation . It is a great risk for your body to perform the tests , also it need a lot of special training plus the instruments are very expensive !!!
