The first whole-body radiation counter capable of recording separately the amount of radiation in 18 areas of the human body is now in operation at the National Institutes of Health, the NIH has announced.

The new instrument, an experimental model especially designed and constructed for NIH, is able to detect the most minute amount of radiation material within the body and to determine its location with precision, according to the NIH.

It is more flexible and more sensitive than any other counter built to date, NIH researchers said.

It is so sensitive that it can easily detect radiation emanating from an amount of isotope one-hundredth the size of the average therapeutic dose, researchers said.

Two to three minutes are required for the instrument to compute and record the total amount of radiation in the body. More detailed studies and analyses may take half an hour or more.
