The French scale, also known as the French gauge or Charrière system, is a widely used measurement system for the size of catheters.It is commonly abbreviated as Fr but may also be abbreviated as Fg, FR or F, and less frequently as CH or Ch (referencing its inventor, Charrière).
It is more pronounced than the lanthanide contraction because the 5f electrons are less effective at shielding than 4f electrons. [1] It is caused by the poor shielding effect of nuclear charge by the 5f electrons along with the expected periodic trend of increasing electronegativity and nuclear charge on moving from left to right.

The micrometre (SI symbol: μm) is a unit of length in the metric system equal to 10 −6 metres ( 1 / 1 000 000 m = 0. 000 001 m). To help compare different orders of magnitude, this section lists some items with lengths between 10 −6 and 10 −5 m (between 1 and 10 micrometers, or μm). ~0.7–300 μm – wavelength of infrared radiation
247 Cm has the longest lifetime among isotopes of curium (1.56 × 10 7 years), but is not formed in large quantities because of the strong fission induced by thermal neutrons. Seventeen isotopes of berkelium have been identified with mass numbers 233, 234, 236, 238, and 240–252. [ 58 ]
