Abstract :
Radioactive phosphorus 32P has been used extensively in the assessment of cellular activity. By using mica end-window geiger tubes in contact with surface breast tumors, circadian fluctuations of the 32P content of breast tumors have been demonstrated in vivo. This paper describes the equipment used and summarizes the results obtained.
