Enemy or foe is an individual or a group that is seen as forcefully adverse or threatening. The concept of an enemy has been observed to be basic for both individuals and communities.
A diffractometer (pronunciation: di-frak-'tÃ¤-m&-t&r) is a measuring instrument for analyzing the structure of a material from the scattering pattern produced when a beam of radiation or particles (such as X-rays or neutrons) interacts with it. Principle
SHIMADZU XRD-7000 X-RAY DIFFRACTOMETER 2 Radiation Safety 1,2 -rays produced by the diffractometer pose a very real danger. Human tissue can be severely damaged if exposed to the x-rays used in x-ray diffraction. Long-term, chronic exposures at moderate levels can directly cause a variety of skin disorders, and chronic relatively low-level exposures may be a factor resulting in increased cancer risk in exposed personnel.
