In the last 20 years the use of atom medicine has become so widespread that every big medical centre uses some form of it in diagnosis and treatment. Thousands of hospitals all over the world have had very successful results with radioactive iodine for thyroid cases.
The chief medical use of radioisotopes is against cancer. Every year thousands of cancer patients are being treated with radio-cobalt, which in many ways is better than X-ray treatment.

The most common and serious forms of organic heart disease are those affecting the coronary arteries, which supply blood to the heart. These diseases are usually associated with high blood pressure (hypertension) and hardening of the arteries (arteriosclerosis). A heart attack is usually a case of coronary thrombosis. Heart failure may be a late consequence of any of these conditions, or others. This group of heart troubles is predominantly, but not exclusively, associated with the middle and later years of life.

In some cases it is necessary to make a brain operation, cutting several nerve tracts. In 1958 surgeons made this operation for the first time with an “atomic knife” – a proton beam that required no cutting into the brain. Usually such operation required weeks of preparation and many weeks of recovery. The atomic operation took about two hours; as soon as it was over, the patient walked off to a meal. He did not feel any pain and only said that he was tired from sitting in the same position for two hours. During the operation the patient was rotated from time to time so that the beam from synchrocyclotron could strike the brain at different angels. The surgeons directed the beam from another room, giving the patient instructions from time to time by the telephone.
The proton beam was 10 mm wide and 2 mm thick.

Two American biochemists, Stanley H. Cohen and Herbert W. Boyer, inaugurated the science of genetic engineering – and its associated field of biotechnology – in 1973. They showed that it was possible to break down DNA into fragments and combine them into new genes, which could in turn be placed in living cells. There they would reproduce each time a cell divided into two parts.

When Dr. Ian Wilmut introduced the world to the first successful clone of an adult mammal – a seven-month old Finn-Dorset lamb named Dolly – a new frontier in science opened wide.
In 1996, Dolly became the first large animal to be cloned from genetic material extracted from an adult cell.
Scientists inserted a cell from a ewe’s udder into an egg from the same animal after removing the egg’s DNA. The bioengineered embryo was implanted in the ewe’s womb and Dolly developed as a clone. Her birth at the Roslin Institute in Scotland was announced in 1997 and caused an international sensation.

In some cases it is important for the surgeon to know whether an injured bone has “died” from loss of blood supply.
Few years ago it was necessary to wait several months, and sometimes even a year, for the accurate diagnosis that made treatment possible. Now surgeons have discovered how to find in a few minutes whether the bone has “died”. It is done by using a radioisotope – Sodium 24. When this isotope is pumped into the injured bone, it keeps its radio-activity if the bone is “dead”. But if the bone is still living, the blood carries away the radioisotope within ten minutes.
By measuring the amount of radio-activity left in the bone, the surgeon gets the information about the condition of the injured bone.
