Is radiocarbon dating perfectly accurate

(Refer Historical Carbon Dioxide record from the Vostok ice core).The reader should take note that the Law Dome ice cores dating back to 1000 years were dated by counting the annual layers.But according to the literal interpretation of scripture, the age of the earth is only 6000 years, implying that steady state has not been reached.To do Radiocarbon dating, we need to know the ratio of C records from the Law Dome Ice Cores by Etheridge et al).

"We went looking to test the assumption behind the whole field of radiocarbon dating," Manning said."We know from atmospheric measurements over the last 50 years that radiocarbon levels vary through the year, and we also know that plants typically grow at different times in different parts of the Northern Hemisphere.
"There has been much debate for several decades among scholars arguing for different chronologies sometimes only decades to a century apart—each with major historical implications. may all be inaccurate since they are using the wrong radiocarbon information," Manning said.
