without the use of gold, man could not have visited the moon..........

Gold is used in circuits that are fitted into the spacecrafts as it is an excellent conductor. Also, many parts of spacecrafts are fitted with gold coated polyester film that reflects infrared radiations, and helps control the temperature inside the vehicle.Gold is significant in space travel and since space travel has increased over the years, so has the demand for gold. 
                                    
   It is used in almost all space vehicles designed by NASA which are worth billions of dollars. In the construction of the popular US Columbia Space Shuttle, around forty eight kilogram's of gold was used for objects such as reflectors, conductors and in the brazing of alloys.Gold is also used in the helmets worn by astronauts.


                             Although gold is an expensive element, its myriad qualities make it vital in the use of space vehicles. 


                                      Had it not been for gold, space travel might not have been such a                                                    
                                                           

                                         such a successful mission as it is today!!!!!!!!!

do u know what 916 KDM gold means...........

KDM: Gold Jewelry from some places is / was marked with a KDM Stamp which means that the Jewelry was soldered with Cadmium. Cadmium called 'Kadium' in some places and marked KDM was traditionally used in soldering of gold jewelry for its good properties of liquidity and melting at lower temperatures, which is not the case any more as Cadmium is known to create toxic fumes when melted, which are very dangerous to health, over a period of time and may be harmful to humans, making the gold jewelry.


 some countries have banned the use of Cadmium in workshops. Jewelers in many parts of the world now use gold solders, which are free from Cadmium. Please note that the wearer of the gold jewelry is not harmed, this issue only concerns the manufacturing process. Also note that using any type of gold solder either KDM (Cadmium) or other gold solder, to make the jewelry does not guarantee the purity of gold, as the purity is a representation of the percentage of gold in any metal.


                                                              While Standard gold is 24 carat (100% pure gold), in India, it is 22 carat or 916, ie 91.6% pure gold and the rest includes metals like copper and silver.

gold treats cancer

It is not widely known but radiactive gold was used in the treatment of cancer many years ago. In some cases, new technologies rely on the ability of tiny gold nanoparticles to specifically collect in a cancerous tumour by passing through the inherently leaky blood vessels attached to a tumour. So, when injected into a patient, there is a means by which a potent anti-cancer compound attached to a gold nanoparticle, can be directly and accurately delivered to a tumour whilst avoiding healthy body tissue. Such an effective drug delivery mechanism with reduced toxicity is considered to be a major step-forward. Why usegold as the delivery mechanism? Well gold has a major advantage in being a very biocompatible metal. For example, colloidal gold has been safely used for over 70 years to treat rheumatoid arthritis, and many hundreds of years as a dental restoration..http://www.azom.com/Details.asp?ArticleID=4946..for more info logon to this site
