Ernest Rutherford discovered radiation. Alpha is most harmful is ingested, it cannot penetrate the sign, nor paper or metal or lead, beta is able to penetrate paper and metal, and gamma, the most harmful of the three is able to penetrate paper, metal, lead, and skin. beta can penetrate the skin after a long period of time.
Radiation strength : means the define area in which the signal must be strong for communication in between transmitter and receiver device
EM radiation higher in frequency than violet visible light but lower in frequency than soft x-rays.
Thermal Energy: Substance that has energy from the movement of its particles.
In weight it is means it is not heavy. In physics it is electromagnetic radiation that can produce a visual sensation.
