Cobalt 60 Mode of decay: Beta particles and gamma radiation Chemical properties: Metallic solid that can become magnetically charged What is it used for? Co-60 is used medically for radiation therapy as implants and as an external source of radiation exposure. It is used industrially in leveling gauges and to x-ray welding seams and other structural elements to detect flaws. Co-60 also is used for food irradiation (http://www.cdc.gov/ncidod/dbmd/diseaseinfo/ foodirradiation.htm)‚ a sterilization

* Hormones which regulate the secretory action of other glands. * Because of this‚ the anterior pituitary is often called the master gland * These six hormones are: * Growth hormone (GH) * Prolactin (PRL) * Thyroid stimulating hormone (TSH) * AKA thyrotropin * Adrenocorticotropic hormone (ACTH) * Gonadotropic hormones * Follicle stimulating hormone

below the thalamus just above the brainstem. Pituitary: Is location within the sella turcica which is a dip in the sphenoid bone. Structures are tropic hormone and neurohypophysis. Thyroid: A) Location: anteriorly‚ above the thyroid glad. B) Structures are the isthmus connecting the two lobe and thyroid follices and network of capillaries Adrenal: A) Location: sit on superior border of each kidney‚ it has 3 regions which are the capsul‚ adrenal cortex and adrenal medulla. Pancreas: A)

more than 20 major hormones straight into the bloodstream and from here they can be transported to the cells in other parts of the body. There are many major glands that make up the endocrine system and these include the: hypothalamus‚ pituitary‚ thyroid‚ parathyroid‚ adrenals‚ pineal body and the reproductive glands (testes for males and ovaries for females). The pancreas is also involved in secreting hormones which are involved with the maintaining of blood sugar levels within the body. The pancreas

that obesity is caused by thyroid problems yet there are many ways to avoid this‚ there are foods that can’t be avoided that can stop the thyroid problem. There are medicines that will eliminate or control the problem. The thyroid causes the body to make too many proteins that the body does not need‚ and this can cause increased body weight and swelling. It also controls metabolism‚ and can cause you to lose weight too slowly or cause you to lose weight too fast. The thyroid is the number “medical cause”

Uses of radioisotopes Nuclear Power Note: nuclear power works by radioactivity “Radioisotopes are naturally occurring or synthetic radioactive form of an element. Most radioisotopes are made by bombarding a stable element with neutrons in the core of a nuclear reactor. The radiations given off by radioisotopes are easy to detect. Most natural isotopes of relative atomic mass less than 208 are not radioactive. Those from 210 and up are all radioactive.”(Radioisotope - Hutchinson Encyclopedia)
