The isotope chromium-53 is used in isotopic geology for dating.
Radioisotopes for many uses (e.g. medical, industrial, scientific) are produced in nuclear reactors.
The more chromium used in making stainless steel, the softer the alloy becomes, which is undesirable in the manufacturing of surgical instruments. Therefore, the mix required to make quality medical instruments is very specific and has well defined parameters.
o SAPIEN Valve:§ Cobalt Chromium frame with bovine pericardial leaflets§ 58-70wt% cobalt 26-30wt% chromium + small amounts of other alloying metals. The most common alloy for medical implants utilizes the addition of 6% molybdenum.§ The cobalt within Co-Cr alloys forms an alpha phase while the chromium allows the alloy to form a passive oxide layer (Cr2O3) similar to stainless steel. The passivation of the surface allows for high corrosion resistance which is a desirable quality in long term implants.§ Co-Cr alloys have attractive mechanical properties such as high strength and excellent fatigue resistance.§ Problems with Co-Cr alloys are that they are expensive and difficult to manufacture to medical standards. Even with the addition of other alloying agent.
Chromium, in the form of sodium chromate, attaches strongly to the hemoglobin of red blood cells. This makes radioactive chromium-151 an excellent isotope for determining the flow of blood through the heart. This isotope is also useful for determining the lifetime of red blood cells, which can be of great importance in the diagnoses of anemias.© Copyright 1997 James R. Fromm (jfromm@3rd1000.com)

Fission of uranium and plutonium is mainly used to produce electricity, but also smaller reactors are used to produce radioisotopes for medical and industrial use
It provides a good deal of electricity, 19 percent in the US. It also provides useful radioisotopes for medical and industrial use
It is mostly used to generate electricity, that is all large power reactors can do. There are some small reactors designed to enable samples to be irradiated and removed quickly, to provide radioisotopes for medical and industrial use.
short half-lives and be quickly eliminated from the body
It can produce radioisotopes used in diagnosis and treatment of medical conditions
