  • Problem with radiation standards

    Existing standards considerably underestimate the amount of radiation absorbed by a child’s head, say researchers from the US. Radiation absorption is assessed using a model of a head that is based on the head size of the top 10% of US military personnel and is usually referred to as ‘SAM’. This is not an appropriate model to assess radiation absorption of the population, say Om Gandhi and team, because smaller heads absorb more radiation.
