Physics · Food Irradiation Principles

Consider the following statements regarding food irradiation, a modern preservation method used to improve food safety and extend shelf life without the use of high temperatures: 1. It involves the use of ionizing radiation such as gamma rays or electron beams to inactivate microorganisms by damaging their DNA. 2. It is effective in destroying bacteria, parasites, and insects, thereby enhancing the hygienic quality of food. 3. The process leads to a significant rise in temperature of the food, similar to conventional heating methods. 4. It helps in extending shelf life while largely retaining the nutritional value and sensory properties of food. Which of the above statements are correct?
