Thirty years ago, I reported in this column a shocking discovery. Some X-ray machines were exposing patients up to 60 times the amount of radiation needed for some procedures. X-ray equipment was often old, rarely calculated for radiation exposure and some technologists were incompetent. The column resulted in a big crackdown by government health authorities. Now, Transport Canada reports that more than 40 scanners will be installed in Canadian airports. Fortunately, all of these scanners will use "millimeter wave" technology. This means travellers will be exposed to radio frequency waves that produce a three-dimensional image of a person's body to detect hidden weapons or explosives. Radio waves are not the same as harmful X-ray ionizing radiation to be used in the U.S. I've discussed...

Organic food consumption among consumers is becoming popular nowadays. The attitude has emerged in today's modern world due to the increased in awareness of the importance to maintain a healthy lifestyle by consuming foods without unsafe additives, preservatives, flavor and coloring.

In terms of perceived value towards organic food product, most of the research found positive and not less also discovered negative result mainly due the lack of some special value in the eyes of consumers. The research aims to identify the perceived value factor and its impact towards the customers' purchase intention in Malaysia. The findings of the study indicated that out of four factors, on...
