This document discusses occupational radiation safety and protection. It notes that high-energy radiation can damage DNA and cause cancer. It outlines the radiosensitive organs like the reproductive system, thymus gland, eyes, and bone marrow. Children are more sensitive to radiation than adults. The document also discusses radiation protection during pregnancy, dose limits, shielding, and dosimeter badges to monitor radiation exposure. It briefly mentions the concept of hormesis where low doses of radiation may be beneficial.

2. • Why radiation is dangerous for our body? High-energy
radiation, such as x-rays, gamma rays, alpha particles,
beta particles, and neutrons, can damage DNA and cause
cancer.

4. Coordinal principle of radiation
protection

5. Radiosensitivty
• Organs:
• Male and female reproductive system
• Thymus gland/ eyes/ bone marrow
• All glands
• Stem cells
• Radio sensitivity decreases age wise
• Children are more to radiations

6. Radiation protection in pregnancy

7. Dose limits

8. shielding

10. Dosimeter badge

11. • Hormesis:
• a little bit radiation is good for human…..
•Why?

12. Thank you for your attention…
Now please ask questions
Your silencing is due to two reason…
1: your understand all the thing which include in Lec.
2: you will not understand any thing in whole Lec…...
