thousands of time greater than conventional battery sources. Hence‚ there is an urgent need to harvest enormous amount of energy released naturally by the tiny bits of radioactive material. Unlike conventional nuclear power generating devices‚ these batteries do not rely on the fission or fusion reactions and do not generate any radioactive material as by-product. They promise clean‚ safe‚ reliable and almost endless energy without any drop in its yield or efficiency during its entire life span-which

Nuclear Medicine Nuclear medicine has been around for more than 50 years now and stems from the discovery of x-rays and artificial radioactivity. In 1946‚ nuclear medicine made a monumental breakthrough when radioactive iodine led to the complete disappearance of cancer in a patient’s thyroid. Nuclear medicine became widely used in the 1950’s to measure the function of the thyroid‚ to diagnose thyroid disease‚ and for the treatment of patients with hyperthyroidism. By the 1970’s nuclear medicine

Only ten percent of medically used radioactive isotopes used in America are actually produced here in the United States. The other 90 percent we use must be imported from other countries‚ creating a hardship on our medical community who desire to meet growing demand--as well as participate in research activities that might aid in further advances in this field (for both cancers and other disease treatments). Additional benefit * Another benefit of radioactive isotopes is its ability to aid doctors

Making it the most common radioisotope used in diagnosis. Technetium-99 is used as a radioactive tracer and is detected in the body by gamma cameras. Technetium-99 is produced by bombarding Molybdenum with neutrons‚ producing Molybdenum-99. This then goes through a Beta decay with a half-life of 66 hours and produces Technetium. Technetium-99 isn’t stable and therefore turns into Ruthenium-99 through more beta decay. Technetium-99 has a half-life of only 6 hours. This makes it nearly impossible to

There are various types of radiation surrounding us. As human beings‚ we are primarily exposed to natural forms of radiation such as radon‚ cosmic (space) radiation‚ and naturally occurring radioactive elements found in the Earth. We are also exposed to man-made radiation including medical radiation. Nearly half of the radiation in which the US population is exposed to comes from medical sources such as CT scans‚ x-rays‚ and nuclear medicine. In 1899‚ Ernest Rutherford discovered that the radiation

Alpha‚ beta and gamma radiation The degree to which each different type of radiation is most dangerous to the body depends on whether the source is outside or inside the body. If the radioactive source is inside the body‚ perhaps after being swallowed or breathed in: Alpha radiation is the most dangerous because it is easily

There are many types of radiation and radioactive emissions in the world wide that can be used in medicine. Iodine-131 has a big effect and usage for medicine where it has 53 protons‚ 53 electrons and 78 neutrons. Iodine-131 has varied uses in medicine where it is utilized as a part of atomic pharmaceutical restoratively and can likewise be seen with symptomatic scanners in the event that it has been utilized remedially. Iodine-131 they can be promptly followed even in moment amounts with such discovery
