Gray (unit) Gray (unit) The gray (symbol: Gy) is a derived unit of ionizing radiation dose in the International System of Units (SI). It is defined as the absorption of one joule of radiation energy per kilogram of matter. It is used as a unit of the radiation quantity absorbed dose which measures the energy deposited in a unit mass at a certain position, and of the radiation quantity kerma, which is the amount of energy that is transferred from photons to electrons per unit mass at a certain position. The corresponding cgs unit to the gray is the rad (equivalent to
Energy and Climate Partnership of the Americas to reduce both conventional pollution and the carbon footprint of fossil fuels, as well as best practices on land use management. Energy Infrastructure: Foster modernized, integrated, and more resilient energy infrastructure, particularly electrical grids and gas pipelines. Energy Poverty: Target urban and rural energy poverty with strategies to promote sustainable urban development and improve access to modern clean energy services and appropriate technologies in rural areas that can improve public health and reduce fuel wood use that benefits forest management. Regional energy integration:Promote regional energy coordination, cooperation, or harmonization (where feasible) and interconnection between and among countries in the Americas,
