May 15, 2013· Naturally occurring mineral for thermoelectric power generation. In particular, it is desired to recover and use intermediatetemperature (300500 ℃) waste heat from automobiles and plants. Promising thermoelectric materials for the temperature range consists of toxic elements such as lead (Pb) and this fact is an obstacle to practical use.
SC 52: Radiation Protection for Naturally Occurring Radioactive Materials (NORM) and Technologically Enhanced NORM (TENORM) from Oil and Gas Recovery Description NCRP SC52 was established in 2015 to address "Radiation Protection for NaturallyOccurring Radioactive Materials (NORM) and TechnologicallyEnhanced NORM (TENORM)" for oil and gas recovery.
NORM is an acronym for naturally occurring radioactive materials, which include radioactive elements found in the environment. Longlived radioactive elements of interest include uranium, thorium and potassium, and any of their radioactive decay products, such as radium and radon.

Non – metallic (synthetic materials ) These are non – metallic materials that do not exist in nature, although they are manufactured from natural substances such as oil, coal and clay.
Cinnabar is a naturally occurring mercury sulfide found in and around Santa Clara County. It was the main ore of mercury mined by many of the California mining companies for the past 150 years. Cinnabar is generally found in a massive, granular, or earthy form, and is bright scarlet to brickred in color.
The "Encyclopedia of Common Natural Ingredients" says a natural product is defined as "a product that is derived from plant, animal or microbial sources, primarily through physical processing, sometimes facilitated by simple chemical reactions such as acidification, basification, ion exchange, hydrolysis, and salt formation as well as microbial fermentation.
