In 2015, though, Iran permitted the opening of 150 new treatment centers to help deal with the problem.
About 60 percent of the Iranian population is under age 40, making the youth of Iran an influential force now and in the future.
They like Western cultures and want the freedom to express themselves.
President Hassan Rouhani, who was elected in 2013 with a large youth majority, has often advocated leniency for Iran’s young people.
There are still some points which can’t be understood without expressing those verbally.The calcium-potassium age method is seldom used, however, because of the great abundance of nonradiogenic calcium in minerals or rocks, which masks the presence of radiogenic calcium.On the other hand, the abundance of argon in the Earth is relatively small because of its escape to the atmosphere during processes associated with volcanism. This dating method is based upon the decay of radioactive potassium-40 to radioactive argon-40 in minerals and rocks; potassium-40 also decays to calcium-40.Thus, the ratio of argon-40 and potassium-40 and radiogenic calcium-40 to potassium-40 in a mineral or rock is a measure of the age of the sample.Iran’s laws closely follow edicts given by strict Muslim clerics who took over the country in 1979.However, before the Shah was removed from power, Iranian culture was quite progressive and Westernized.Today, girls wear makeup and show more of their faces by pushing back their veils.In public, couples hold hands—an act which was once strictly forbidden—and listen to Western pop music.The potassium-argon dating method has been used to measure a wide variety of ages.The potassium-argon age of some meteorites is as old as 4,500,000,000 years, and volcanic rocks as young as 20,000 years old have been measured by this method.
