Since we cannot see, smell or taste radiation, we are dependent oGeiger Counters and Radiation Detectors to indicate the presence of ionizing radiation. Radiation is energy traveling in the form of particles or waves in bundles of energy called photons. Some everyday examples are microwaves used to cook food, radio waves for radio and television, light, and x-rays used in medicine.
Radioactivity is a natural and spontaneous process by which the unstable atoms of an element emit or radiate excess energy in the form of particles or waves. These emissions are collectively called ionizing radiations. Depending on how the nucleus loses this excess energy either a lower energy atom of the same form will result, or a completely different nucleus and atom can be formed.
Ionization is a particular characteristic of the radiation produced when radioactive elements decay. These radiations are of such high energy that when they interact with materials, they can remove electrons from the atoms in the material. This effect is the reason why ionizing radiation is hazardous to health, and provides the means by which radiation can be detected.

Most of us go through the day unaware that lurking above our heads or hallways may be devices that are radioactive. At the end of their life cycle, do these become items hazardous wastes for disposal? Which ones pose a health hazard to us? As taxpayers, we want to be able to look to the feds for our safety. While our government is supposed to authorize the safe levels of radioactive emissions from such devices, it seems the feds do not widely advertise the proper method of disposal of these same hazardous wastes.
ReplyDeleteRadiation is all around us. In the sun's ray, at the airport, on the cell phone, near the microwave. We heard as kids that too much of anything can't be good, and that applies to various levels of radio waves. The big three that we train on in the environmental services field are X-rays, Gamma rays, and Beta rays. Some rays can be protected against by something as simple as paper, and some need dozens of feet of dirt and concrete, or lead sheet. However, too much radioactive dosage at one time for a specific ray can cause acute or chronic burns to organs, genetic mutation, and possibly even a private invite to the Pearly Gates themselves!
While most homeowners in New England are aware today of the presence of Radon Gas that is emitted from the granite with which their cellar foundations are made, many are not aware that granite emits a bit of radioactivity as well. A property manager or homeowner would be wise to install Radon Gas detectors that can be purchased at any hardware store for the protection of the inhabitants. While Radon Gas is dangerous over a period of time, open ventilation is a simple enough way to rid the facility of any gas buildup. However, for radioactivity, a Geiger counter is required to check for levels of radioactive isotopes. Thankfully, over a long period federal and state oversight, there has not been sufficient evidence to show dangerous levels of radioactivity in most common granite buildings, and so we have not been focusing on that type of threat. In New England, many of the courthouses and public historic buildings were constructed of Maine, Vermont, and New Hampshire granite. Jokingly, we citizens thought maybe it was the radiation that was causing poor fiscal decisions at the Capitol, but sadly, no!
