Good evening dear,
In year 1911, a gentleman known as George de Hevesy , the first practical application of “radioisotopes” was invented by him a Hungarian man.
The real life story starts , when he was a young student working in Manchester, he was studying “naturally radioactive materials”.
He was not having much money, he lived in modest accommodation and ate meals with his landlady.
One day, he started having some suspect, the meals which appears regularly might happened to be the leftover from preceding days or even weeks.
But , how could be sure, the solution was to try and confirm his suspicious de Hevesy , he put a small amount of radioactive material into the remained meal.
Several days later, when he ordered the same menu food.
This time he used a “Simple radiation detection instrument”, a gold leaf electroscope – to check if the food was radioactive.
Reality was confirmed De Hevesy’s suspicions was right.
In year, 1943 , George de Hevesy won The Noble Award.
In year 1959, George de Hevesy won Atoms for Peace Award .
His incident was the first use of radioactive tracers, now routine in environment science.
This is something very interesting in life.
While advancing our concept to use radioactive technology with the ideology of George de Hevesy for our future.
Thank you so much for sharing your time with me.
