How is radioactive dating used
Classical Electromagnetism cannot explain radioactivity. It's a spontaneous and random phenomenon whereby nuclei of certain chemical elements like Uranium, radiate gamma rays (high frequency electromagnetic radiation), beta particles (electrons or positrons) and alpha particles (Helium Nuclei).
By the emission of these particles and radiation, the unstable nucleus gets converted into a stabler nucleus. The Term 'Radioactive' - A Misnomer A radioactive element is a fundamental element whose atomic nuclei demonstrates the phenomenon of radioactivity.
Time factors of millions and billions of years is difficult even for adults to comprehend.
However, "relative" dating or time can be an easy concept for students to learn.
Neutrons are neither positively charged, nor negatively charged, they are neutral particles. As you might remember from high school physics, like charges repel each other while unlike charges attract each other.
radiation sickness,harmful effect produced on body tissues by exposure to radioactive substances.
The biological action of radiation is not fully understood, but it is believed that a disturbance in cellular activity results from the chemical changes caused by ionization (see.....
Today, the city of San Francisco has set its sights on erecting a second downtown there.
But Treasure Island’s fate in the intervening decades—and a long-secret legacy of radioactive waste left behind—has complicated those plans.
