Radiations and Radiopharmaceuticals
Properties of Alpha (α), Beta (β), and Gamma (γ) Radiations
- Alpha (α): Helium nuclei (+2 charge), high mass, low penetration, high ionization. Stopped by paper.
- Beta (β): High-speed electrons/positrons (±1 charge), small mass, moderate penetration/ionization. Stopped by aluminium.
- Gamma (γ): Electromagnetic waves (no mass/charge), speed of light, high penetration, low ionization. Stopped by lead/concrete.
Precautions for Radiopharmaceuticals
- Use protective gear

DEFINE CONSTRAINT SATISFACTION PROBLEM CSPS AND EXPLAN THEIR COMPONETS WITH EXAMPLE
A Constraint Satisfaction Problem (CSP) is a problem in Artificial Intelligence where the objective is to assign values to a set of variables such that all specified constraints are satisfied. CSPs are commonly used in planning, scheduling, resource allocation, map coloring, and puzzle-solving applications.
A CSP is represented as a triple:
CSP=(X,D,C)
Where:
X = Set of variables
D = Domain of values for each variable
C

Mobile Network Architectures: UTRAN, GSM, LTE, and VANET
UTRAN and UMTS Architecture
UTRAN (UMTS Terrestrial Radio Access Network) is the radio access part of the UMTS (Universal Mobile Telecommunications System). It provides wireless communication between user equipment and the core network. UTRAN is responsible for radio resource management, handover control, power control, encryption, data transmission, and maintaining the quality of service.
Key Components of UTRAN
