What the notification says

The notified draft Mexican Official Standard establishes the criteria and factors for calculating the dose equivalent and the effective dose equivalent. These values allow the risk of exposure to ionizing radiation to be quantified, thereby protecting the health and lives of workers in the workplace. It also defines basic concepts such as absorbed dose, radiation quality factors and tissue weighting factors, and includes reference tables for different types of radiation and organs of the human body.Compliance with the specifications will be reviewed through documentation based on the Conformity Assessment Procedure included in this draft amendment.
