In 1942, Marinelli established the principles for dosage determination of internal radioisotopes in the human body. In 1946, he developed the systematic dosimetry to distribute radioactive iodine to treat all locations of the metastases of a patient's thyroid cancer. This breakthrough was followed by

This made possible the comparison of xrays and gamma rays, later useful to evaluations of cancer therapies. By 1933, he coauthored his first publication with
