Y. Takizawa et al., AN IMPROVED METHOD FOR TC-99 ANALYSIS AND APPLICATION TO HUMAN TISSUES, Journal of radioanalytical and nuclear chemistry, 197(1), 1995, pp. 51-56
Technetium-99 was determined in nine human liver samples collected fro
m autopsy of the subjects at the Niigata Prefecture Institute for Canc
er Research Hospital. Even by using a very sensitive analytical proced
ure Tc-99 was detected in only one human liver sample. Though Tc-99 wa
s detected in only one liver, nonetheless it is very important to stud
y its distribution in the human body because of the contribution from
fallout of nuclear weapons tests and prevalent use of Tc-99m in nuclea
r medicine.
