放射性同位素已經用於医学的各方面——新陈代謝的研究,人体內部工作的探討,以及各式各样的療法。在研究血液失常的血液学方面,最普遍使用的媒介是磷酸鈉,它含有磷的放射性同位素.放射性磷的溶液是內服的——它們無味無臭,也容易被有机体所同化。这种方法对於治療紅血球增多症(紅血细胞產生过剩)效力最大,已被証明。 Radioisotopes have been used in all aspects of medicine - research in metabolism, in-house work, and a wide variety of therapies. The most commonly used medium for studying the hematology of hematologic disorders is sodium phosphate, which contains radioactive radioactive isotopes of radioactive phosphorus, which are administered orally - they are odorless and odorless and are easily assimilated by organisms. This method has been shown to be most effective in treating polycythemia vera (excess red blood cell production).
