Descriptor tecnecio
Entry term(s) tecnecio 99m
Scope note: El primer elemento producido artificialmente y un producto de la fisión radiactiva del URANIO. Su símbolo atómico es Tc y su número atómico 43. Todos los isótopos del tecnecio son radiactivos. El Tecnecio 99m (m=metaestable), que es un producto de la desintegración del molibdeno 99, tiene un periodo de semidesintegración de alrededor de 6 horas y se utiliza en el diagnóstico por imagen como marcador radioactivo. El Tecnecio 99, un producto de la desintegración del Tecnecio 99m, posee un periodo de semidesintegración de 210.000 años.
