Internal Examination of a Newly Hatched Alligator. A professional can determine the gender of a very small baby alligator, 6 to 10 inches long. One method is to place the creature on its back and hold open his vent with round-tipped tweezers or forceps, with a helper's assistance.
Technetium is the only element below uranium that does not exist on Earth. It is a synthetic (man-made) element produced in a particle accelerator. For many years, chemists knew that an element with atomic number 43 must exist, based on an empty spot in the periodic table.
One of these purposes is the Technetium-99m Generator.Technetium-99m, a man made element and a type of technetium isotope, has been used as a radioisotope since 1958. Since all isotopes of technetium are radioactive so is technetium-99m.The radioisotope is used to diagnose diseased organs. The injection of the technetium-99m isotope gives off a certain type of radiation which show doctors which areas of the organ is diseased without causing radiation damage to the patient.ne of these purposes is the Technetium-99m Generator.Technetium-99m, a man made element and a type of technetium isotope, has been used as a radioisotope since 1958.
