ISOTOPES IN THERAPY AND DIAGNOSIS

Table 48. Potentially Valuable Tracer Isotopes, Especially Those of Elements 

 for Which Biological Studies Have Not Yet Been Carried Out 



The elements marked with an asterisk* appear in Table 46. 



In connection with the rarer stable species listed here it should be understood that the 

 one to several more abundant species, when prepared in pure form or enriched, may in 

 some cases find application as tracers, either independently or, in the case of multiple 

 labeling experiments, in conjunction with the rarer species.
