The quantity of matter as described by its energy equivalence
Mass
Force exerted on a body under influence of gravity
Weight
Any type of radiation that is capable of removing an orbital electron from the atom with which it interacts
Ionizing radiation
Restricting the useful xray beam to the part of the body, spares unnecessary tissue exposure, and improves contrast
Collimation
What year did Roentgen win first Nobel Prize in physics
1901
What year did Roentgen discover X-rays
1895
What year was the Coolidge hot cathode X-ray tube introduced
1913
What year was the snook transformer developed
1907
Why was the discovery of xray such an amazing event in human history
The discovery was accidental
No fewer than a dozen contemporaries had observed X-rays before Roentgen but they hadn’t realized the significance
Roentgen followed his discovery with such scientific vigor that within a little over a month he had described X-rays with nearly all the properties we recognize today
