초에 Holzknecht는 선량을 측정하는 ‘Chromoradiometer’를 고안하였는데 이것을 염화칼륨(Potassium chloride)과 탄산나트륨(Sodium carbonate)의 혼합물이 X선에 의해 변색되는 정도 차이로 선량을 측정하는 방법으로 최소의 변색을 나타내는 양을 ‘1H’로, 피부 홍반을 일으킬 수 있는 양을 ‘3H’로 표시하였다.

3G network. But the newest technology coming out is 4G coverage. 4G network promises faster connection and better coverage. But full 4G connection is not completely ready, and because of that, 3G coverage still is the best choice for Smartphone users. For our purpose, we analyzed Mobile Phone market share in Korea.
Size of industry (Standard: 2011. 10.30)
- Total Number of Mobile Phone ab
Products are banned from being placed in a landfill either because they present a health risk, example the cathode ray tubes (CRTs) in computer monitors, or because they take up too much space.
Products banned from landfills are: motor oil, household batteries, household appliances, paper products, tires, and some medical and electrical equipment.
Product ban represents a new reverse logistics
