The provided text offers a comprehensive analysis of radiation's health impacts, distinguishing between non-ionizing and ionizing radiation based on their energy levels and mechanisms of interaction with biological tissue. It explains that ionizing radiation, the focus of health concern, damages DNA through direct and indirect action, leading to cell repair, death, or mutations. The text categorizes clinical consequences into deterministic effects, which have a dose threshold and whose severity increases with dose (e.g., Acute Radiation Syndrome), and stochastic effects, which are probabilistic with no assumed safe threshold (primarily cancer). Furthermore, it details both natural and man-made sources of radiation exposure, highlighting radon inhalation and medical procedures as major contributors, and concludes with an explanation of radiation measurement units and the ALARA principle for protection, emphasizing time, distance, and shielding.
