Abstract: A system for treating radon in the air including at least two carbon electrodes. Each carbon electrode is formed from a mixture of activated carbon, gilsonite, and zeolite which is extruded into the shape of an elongated rod. Positively-charged radon ions in the air are attracted to the electrodes. There is also provided a method for removing radioactive radon isotopes from the air including the steps of: (1) providing at least two carbon electrodes formed from activated carbon, gilsonite, and zeolite; and (2) initiating a chemical reaction between the activated carbon and the radioactive radon isotopes to half-life the radon isotopes into non-radioactive isotopes.

Abstract: An estimated delivery date model determines an estimated delivery date for a shipment of a product to a consumer. For example, a built-to-order information handling system shipped through plural shipping providers has an estimated delivery date determined to provide early notice of the shipment to the consumer. The delivery date is estimated from a manifest for the product based on time in transit adjusted for predicted delays, such as in hubs or due to non-shipping days.
