Sometimes we used it in the hospital so as to take an x-ray and sometimes we used it in the war.

After a while, someone named Marie Curie and his husband Pierre Curie found polonium and radium, while they was experimenting. Only one ne of them, polonium emitted more radiation than uranium.



 Alpha rays can't penetrate behind peaper. After beta rays pass from the paper, they can't penetrate the aleminum plate. Gamma rays penetrate the papar, aleminium and lead plate, but it's strength decreases. Alpha, beta and gamma may be mortal for a person, but all types of radiation are not harmful...

For example, NASA gave tasks to Voyager 1 so as to explore the Jupiter and Saturn, apart from this, it's missions were expore the moon and ring of Jupiter and Saturn and Voyager 2 was the first spacecraft that expore Neptune and Uranus. Anyway, our topic is not Voyager 2, let's turn Voyager 1. It moved away from earth day by day and it is still moving away our earth right now. Acording to scientists, Voyager 1 was the human-made object furthest from earth. Voyager was useing nuclear enegy, this is why, Voyager will run out of it's enegy. There will be no energy so as to activate it's device between 2025 and 2030   We learnd something about Jupiter and Saturn than...
