Core Concepts in Radiation Physics, Solar Cells, and Electromagnetism
Radiation Interaction with Matter
1. Alpha (α) Particles
- Heavy, positively charged particles.
- Interact strongly with matter, leading to high ionization.
- Lose energy quickly and stop within a few centimeters of air.
2. Beta (β) Particles
- Fast-moving electrons.
- Moderate interaction, resulting in moderate ionization.
- Can travel a few meters in air.
3. Gamma (γ) Rays
- Electromagnetic waves (no mass, no charge).
- Weak interaction, causing low ionization.
- Travel long distances and penetrate deeply.
Penetrating Power

Neurons: Structure and Function
Neurons are the basic units of the nervous system. They have four functional zones:
- Input: Dendrites receive information from other cells.
- Integration: The cell body (or soma) integrates the information it receives.
- Conduction: A single axon conducts output information away from the cell body as an electrical impulse.
- Output: Axon terminals at the end of the axon communicate activity to other cells.

Environmental Management and Ethics in Modern India
Impact of Human Population Growth
Human population growth significantly impacts the environment, human health, and overall welfare. Rapid population increase leads to higher demand for natural resources such as water, land, and energy, resulting in deforestation, habitat destruction, and resource depletion. This accelerates environmental degradation, including pollution, loss of biodiversity, and climate change. [1]
The strain on resources also affects human health by increasing exposure to pollution,
