Uranium is weakly radioactive because all its isotopes are unstable (with half-lives of the 6 naturally known isotopes, uranium-233 to uranium-238, varying between 69 years and 4.5 billion years).
The median annual wage for occupational therapy assistants was $59,010 in May 2016. The median wage is the wage at which half the workers in an occupation earned more than that amount and half earned less. The lowest 10 percent earned less than $39,160, and the highest 10 percent earned more than $80,090.
However, the story on the educational front is quite different. In 2006, 5,449 students graduated from occupational therapy degree programs in the US. In 2010, 7,804 students graduated from occupational therapy schools. Thus, in 4 years, there was a 43% growth in the number of occupational therapy graduates. The growth nationally for students graduating from institutions of higher learning in general has been 12% from 2006 to 2010.
