Match each unit used in dosimetry to its definition.Group of answer choicesSI unit of absorbed dose, equal to 1 joule of energy absorbed per kilogram of materialUnit of radiation exposure, equal to the production of 2.58x10-4 coulombs of charge produced by the radiation per kilogram of dry air through which the radiation passesSI unit of activity, equal to one radioactive decay per secondOlder unit of activity, defined to be 3.7x1010 transformations per second, which is approximately the activity of one gram of radiumUnit relating absorbed dose to the degree of biological damage caused by a particular type of radiation

For each quantity in the table below, write the symbol of the SI unit in which it would usually be measured.quantity unit symbolThe level of natural background radiation at the top of Longs Peak, outside of Denver, Colorado.

Write a note on Radiation pattern measurement.

The scientific unit of measurement used to measure the dose received from radiations, such as X-rays or background radiation, is the millisievert (mSv). The table shows the X-ray dose resulting from CT scans of various parts of the body.

Part of the body X-ray dose in mSv Time it would take to get the same dose from background radiation Abdomen 9.0 3 years Sinuses 0.5 2 months Spine 4.0 16 months A student suggests that the X-ray dose and the time it would take to get the same dose from background radiation are directly proportional. Use calculations to test this suggestion and state your conclusion.
