UNIVERSAL RADIATION PROTECTION SYSTEM (URPS); A NATURAL GLOBAL STANDARDISED TREND FOR HUMAN EXPOSURE CONTROL IN 21st...

Area of Science:

• Radiological Protection
• Radiation Health Physics
• Environmental Health

Background:

• Current global radiological protection systems have numerous deficiencies.
• Existing frameworks struggle to uniformly address risks from diverse radiation sources.
• There is a need for standardized, internationally applicable radiation protection methodologies.

Purpose of the Study:

• To propose a novel Universal Radiation Protection System (URPS) Hypothesis.
• To establish principles for equal human health-effect risks per unit radiation dose from both natural background (NBG) and man-made sources.
• To develop a standardized, integrated dose system for comprehensive individual exposure assessment.

Main Methods:

• Application of equal human health-effect risk principles per unit dose.
• Development of a 'standardised integrated dose system' emphasizing national NBG doses.
• Introduction of a 'cause-effect conservation principle' for epidemiological risk estimation.
• Hypothesizing radiation fractionation weighting factors (WF) and a 'URPS Model' to bridge linear no-threshold and hormesis models.

Main Results:

• The URPS Hypothesis offers a new philosophy and methodology for radiological protection.
• It integrates NBG doses into a standardized system for individual dose assessment.
• The proposed model bridges existing radiation dose-response models.
• Example dose limits for workers are presented within the URPS framework.

Conclusions:

• The URPS Hypothesis provides a standardized approach to radiation protection, independent of source or country.
• It aims to protect workers, patients, the public, and the environment through consistent methods.
• The system is designed for effective human exposure control in the 21st century.
