Principles of radiation biology in
Radiological contamination
Ionizing radiation
focuses on the effects of ionizing radiation (eg. X-rays, gamma rays, etc)
Internal radiation Exposure
Study the absorption, distribution, and biological effects of the materials in the body.
It involves the understanding how different isotopes behave in body and their irradiation potential in organs and tissues
Dose-Response Relationship
Address the relationship between the radiation dosage and the biological response
It helps to determine the risks associated with different level of exposure.
Stochastic Effects
Quantify the risks of stochastic effects and understand the underlying mechanisms
Random biological responses that do not have a dose threshold below which they are considered safe
Deterministic Effects
Study the dose thresholds, mechanism and factors influencing this effect
Non-random biological responses that occur above certain threshold dose
Radioactive Decay
Study the decay rate and process of radioactive isotopes in radiological contamination
Exposure Pathways
Inhalation
Inhaled radioactive particles enter the respiratory system and are deposited in the lungs / absorbed into the bloodstream and irradiate other organs and tissues
Ingestion
The consumed radioactive materials enter the Gastrointestinal Tract / absorbed into the bloodstream and irradiate other organs and tissues
External irradiation
Radiation penetrates the body externally and interact with organs and tissues
Protection and Management
Develop strategies to protect individuals and the environment from radiation exposure by implementing measures like decontamination, shielding, and monitoring
Radiological decontamination
Decontamination Techniques
Apply methods t reduce or remove the radioactive contamination from surfaces, objects and environment
Exposure Reduction
Reduce and minimize the exposure of individuals to radiation though shielding and proper use of personal protective equipment
Contamination Assessment
Determine the extent and distribution of contamination in the affected area
Waste Management
Handle and dispose of radioactive waste generated during the decontamination process in a safe way
Contamination Source Identification
Identify and characterize the radioactive materials which cause contamination
Environmental Remediation
Implement measures to restore the environment affected by radiological contamination to an acceptable level
