The most common method for dating artifacts and biological materials is the carbon-14 (14c) method however, it poses a serious problem for deep-time advocates because it cannot be used for dating anything much older than 50,000 years after that time virtually all measureable 14c should be gone1 so a substantial gap exists between dating. The amount of luminescence is proportional to the original dose of radiation received in thermoluminescence dating, this can be used to date buried objects that have been heated in the past, since the ionizing dose received from radioactive elements in the soil or from cosmic rays is proportional to age this phenomenon has been applied in the.
