Today’s History Feature:

Dr. Glenn T. Seaborg

(Apr 19, 1912 – Feb 25, 1998)

💠American Nuclear Chemist

💠Founding Father of Nuclear Medicine

His contributions…

🔸Seaborg was very much inspired by his chemistry teacher, when he was young. Thereby, he became interested in chemistry.

🔸Seaborg began his carrier at the University of California, as a nuclear chemist and discovered around 10 radioactive elements such as plutonium, cerium, nobelium… thus, he created an actinide series in the Mendeleev’s Periodic Tables of Elements.

🔸In fact, his assignments in investigating isotopes greatly contributed to the discovery of more than 100 isotopes of elements.

🔸Subsequently, Seaborg’s elements were being used in the field of medicine and he became a pioneer in nuclear medicine.

🔸His radioactive isotopes utilized in the field of medicine are…

🔹 Iron-59, used to study haemoglobin in human blood.

🔹 Iodine-131, used to treat thyroid diseases (Successfully used personally to prolong the life of his mother who suffered from thyroid disease).

🔹 Cobalt – 60, used as a radiation source for medical radiotherapy.

🔹 Cobalt – 60 Teletherapy machine to treat cancer.

🔹 Technetium-99m, which is a diagnostic radioisotope used widely in…

🔅Tc 99m Sestamibi scans

🔅Tc 99m MAG


🔅Bone scans

🔅Cardiac Ventriculography


🔅Blood pool labelling…

🔸His ground breaking discovery of 10 transuranium elements led him to receive the most prestigious Nobel Prize in Chemistry in 1951 at the age of 39 years.

🔸Conferred as an honour, his element Seaborgium was released in his name in the year 1997. That was the first time, the element was labelled with its scientist’s name (for a living person).

🔸Moreover, Dr. Seaborg advised around ten Presidents of United States from Harry S. Truman to Bill Clinton on nuclear policy.

🔸Dr. Seaborg was actually living with the principle of “There is a Beauty in Discovery.”
