Henri Becquerel of France discovered natural radioactivity a year later.

In 1898, Pierre and Marie Curie isolated the first radioactive elements, radium-226 and polonium-210.

In 1895, a German physicist named Wilhelm Roentgen fortuitously discovered X-rays while experimenting with evacuated glass tubes through which an electric current was passed.

Roentgen discovered he could take a picture of the bones in his hand with the mysterious new rays.

It helps saves lives and provides great benefits to mankind in innumerable ways. If used improperly it can be hazardous to health or cause injury.

Gamma rays are electromagnetic energy waves emitted from the nucleus of atoms and have no charge.

X-rays are the same as gamma rays, except they originate outside the nucleus from processes involving electrons.

Ionization occurs when electrons are dislodged from a neutral atom.

When this happens an atom becomes positively charged and some energy is transferred.

Radiation is emitted by radioactive elements naturally present in the soil, water, and air.

And if you changed your mind, which is perfectly fine, for the love of god just let a dude know. It also drove me nuts when single and basically started a policy of, you flake on me once you're dead to me unless you are the ones making plans next time. And afterwards it's easier to say no on the phone than face to face. Concentrate on getting as many numbers as possible isntead of focusing on getting the one specific number. I have had no problem getting a lot of girls' numbers last year, and they'd always be willing to hang out / go on a date. Then they'd drop of the face of the earth, or change into a completely different person, or what have you. What I don't get is when they have those wild personality changes. It's easier for them this way for the dudes are being pushy with getting a number.… continue reading »
