The document discusses the three main types of radioactive decay - alpha, beta, and gamma decay. It describes the particles emitted in each type of decay and how they affect the atom. It provides examples of specific radioactive isotopes, their decay processes, and half-lives. It also outlines some medical, industrial, and research applications that make use of different radioactive emitters.

Uses of Radioactive Isotopes Including Safety Precautions
The existence of isotopes was first suggested in 1913 by the radiochemist Frederick Soddy,
based on studies of radioactive decay chains that indicated about 40 different species referred
to as radioelements (i.e. radioactive elements) between uranium and lead, although the periodic
table only allowed for 11 elements.
*In nature, most of the elements have many atoms that have the same atomic number but
different mass numbers such atoms of an element are called isotopes. This concept will be more clear from this ppt. And also radioactive isotopes applications and calculation of average atomic mass are explained. Hope it helps! And this is mainly for class ix

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Generating a custom Ruby SDK for your web service or Rails API using Smithyg2nightmarescribd
Have you ever wanted a Ruby client API to communicate with your web service? Smithy is a protocol-agnostic language for defining services and SDKs. Smithy Ruby is an implementation of Smithy that generates a Ruby SDK using a Smithy model. In this talk, we will explore Smithy and Smithy Ruby to learn how to generate custom feature-rich SDKs that can communicate with any web service, such as a Rails JSON API.
Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

Radioactive decay honors
1. It’s better to have a half-life than no life! Radioactive Decay Alpha, Beta, and Gamma Decay

4. The Atom The atom consists of two parts: 1. The nucleus which contains: 2. Orbiting electrons. protons neutrons
5. All matter is made up of elements (e.g. carbon, hydrogen, etc.). The smallest part of an element is called an atom . Atoms of different elements contain different numbers of protons . The mass of an atom is almost entirely due to the number of protons and neutrons . The Atom
6. X A Z Mass number Atomic number Element symbol = number of protons + number of neutrons = number of protons
7. A = number of protons + number of neutrons Z = number of protons A – Z = number of neutrons Number of neutrons = Mass Number – Atomic Number X A Z
8. There are many types of uranium: U 235 92 U 238 92 Number of neutrons Number of protons Z A Number of neutrons Number of protons Z A
9. There are many forms or “isotopes” of uranium: Isotopes of any particular element contain the same number of protons, but different numbers of neutrons. U 235 92 U 238 92 143 Number of neutrons 92 Number of protons 92 Z 235 A 146 Number of neutrons 92 Number of protons 92 Z 238 A
10. Most of the isotopes which occur naturally are stable . A few naturally occurring isotopes and all of the man-made isotopes are unstable . Unstable isotopes can become stable by releasing different types of particles. This process is called radioactive decay and the elements which undergo this process are called radioisotopes/radionuclides .

12. An alpha particle is identical to a helium nucleus. It contains two protons and two neutrons. Alpha Decay

21.
22. Beta Decay A beta particle is a fast moving electron which is emitted from the nucleus of an atom undergoing radioactive decay. Beta decay occurs when a neutron changes into a proton (+) and an electron (-).
23. Beta Decay As a result of beta decay, the nucleus has one less neutron , but one extra proton . The atomic number, Z, increases by 1 and the mass number, A, stays the same.
26. Beta Decay (Thorium-234 to Protactinium, Half-Life : 24 days) Th 234 90 Y A Z + 0 -1 Th 234 90 Pa 234 91 + 0 -1

28. Beta Decay (Bismuth-210 to Pollonium, Half-Life : 5.012 days) Bi 210 83 Y A Z + 0 -1 Bi 210 83 Po 210 84 + 0 -1
29. Beta Decay X A Z Bi 214 83 + 0 -1 Pb 214 82 Bi 214 83 + 0 -1
30.
31. Gamma Decay Gamma rays are not charged particles like and particles. They are released with these particles . Gamma rays are electromagnetic radiation with high frequency. They have 10,000 times more energy than visible light. When atoms decay by emitting or particles to form a new atom, the nuclei of the new atom formed may still have too much energy to be completely stable. This excess energy is emitted as gamma rays (gamma ray photons have energies of ~ 1 x 10 -12 J).
