Concept in urban planning; a city's \
Generally the concept of the neighborhood unit, crystallised from the prevailing social and intellectual attitudes of the early 1900s by Clarence Perry, is an early diagrammatic planning model for residential development in metropolitan areas.
It was designed by Perry to act as a framework for urban planners attempting to design functional, self-contained and desirable neighbourhoods in the early 20th century in industrialising cities.
It continues to be utilised, as a means of ordering and organising new residential communities in a way which satisfies contemporary social, administrative and service requirements for satisfactory urban existence.
Non-SI unit measuring absorbed dose of ionizing radiation
The rad is a unit of absorbed radiation dose, defined as 1 rad = 0.01 Gy = 0.01 J/kg.
It was originally defined in CGS units in 1953 as the dose causing 100 ergs of energy to be absorbed by one gram of matter.
The material absorbing the radiation can be human tissue, air, water, or any other substance.
