50 Economic Dynamics It is possible to estimate λ l 0 for an authentic painting. It is also possible to estimate λ l 0 for the lead in the painting under investigation. If the latter is absurdly large rel- ative to the former, then we can conclude that it is a forgery. A very conservative estimate would indicate that any value for λ l 0 in excess of 30,000 disintegra- tions per minute per gram of white lead is absurd for an authentic painting aged 300years.Using22yearsforthehalf-lifeoflead-210,thenthevalueof λ is(ln2 / 22) and e 300 λ = e (300 / 22) ln 2 = 2 (150 / 11) To estimate the present disintegration rate of lead-210 the disintegration rate of polonium-210 is used instead because it has the same disintegration rate as lead- 210 and because it is easier to measure. In order, then, to authenticate the ‘Disciples at Emmaus’, purported to be a Vermeer, it is established that the disintegration rate of polonium-210 per minute per gram of white lead in this particular painting is 8.5 and that of radium-226 is 0.8.

What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
