Radiation ionises the air which condenses creating a vapour trail, radioactive material is outside the object or person and the irradiated object or person is therefore not radioactive, radioactive material is inside the object or person so therefore the contaminated object or person is radioactive, the average time it takes for the radiation emitted per second to halve or the average time it takes for the number of radioactive atoms to halve.

Thank you for that feedback, Love it, easy to tweak bits to suit both triple and combined, very engaging. GCSESCIENCEREVISION.com - Radioactivity Atomic structure Topic Summary In this topic you need to know: The structure of the atom and how the model has changed over time Radioactive sources and the relative ionising and penetrating powers of Alpha, Beta and Gamma sources Nuclear Equations, including for Alpha and Beta decay It can be dangerous, but is also vital to life. Radioactivity - the spontaneous decomposition or disintegration of a nucleus forming a different nucleus and producing one or more additional particles Radioactive decay. Radioactive decay is a random event The unstable nuclei in some materials will break up, or disintegrate It is impossible to predict exactly which nuclei will decay. neutron-absorbing rods usually made of cadmium or boron that help control the reaction by limiting the number of free neutrons, gaps between the fuel rods and control rods such as carbon or heavy waterused to slow down the fast neutrons produced by fission. Hide Show resource information. the nuclear radiation that arises naturally from cosmic rays and from radioactive isotopes in the soil and air, the amount of radiation the material emits per second, Device used to detect radiation using its ability to ionize matter. Nuclear Radiation - Unstable isotopes emit particles from their nucleus. describe the nature of gamma () particles: very small (photons), can travel through paper and aluminum, stopped partially by lead, are electromagnetic radiation with a very short wavelength, very penetrating and not very ionising, a positively charged particle identical to a helium nucleus, a spontaneous process in which unstable nuclei lose energy by emitting radiation, any form of radiation that has the ability to remove electrons from atoms and molecules, an electron from the nucleus after a neutron, Short wavelength, higher energy electromagnetic waves emitted by the nuclei of radioactive substances, a high-energy neutron is released from a nucleus so mass number decreases by 1, atomic number stays the same, isotope is made, the nucleus loses 2 protons and 2 neutrons therefore the atomic number decreases by 2, the neutrons turns into a proton and electrons however the mass number doesn't change but atomic number increases by one, the nucleus loses a neutron therefore the mass number decreases by 1 however the atomic number stays the same. It is stopped by a few millimetres of aluminium. to IGCSE to physics 0625 Radioactivity Radioactive Decay Radioactive is a spontaneous transformation of an unstable atomic nucleus, in which radiation is released in the form of alpha particles, beta particles, and gamma rays.

This bundle of 9 revision lessons uses a range of exam questions (with explained answers), differentiated tasks and quiz competitions to engage the students whilst challenging their knowledge of the content in the Pearson Edexcel IGCSE Physics specification: used in the treatment of cancer, testing equipment and sterilising medical instruments. IAq] @2K<1yTL8q NoAla:W Nuclear Equations - These show what happens when alpha, beta and gamma are emitted. I am constantly thinking of new ways to engage a student with a topic and try to implement that in the design of the lessons. Electron configuration in an atom affects the chemical and physical properties of an element. Report this resourceto let us know if it violates our terms and conditions. Other materials such as control rods or metal jackets become radioactive due to the neutron radiation and remain radioactive because of long half-lives from the new isotopes. describe the nature of beta () particles: small particles, can travel through paper, stopped by aluminum a few mm thick, are electrons emitted when a neutron splits, fairly penetrating and fairly ionising. Atoms with the same number of protons but different numbers of neautrons. this is difficult as nuclei will repel being like charges. Beta Radiation a device that initiates and maintains a controlled nuclear fission chain reaction to produce energy for electricity. Topic 4: Electricity and Magnetism. , how long will it be before the hydrogen is entirely consumed? Nuclear Radiation - Unstable isotopes emit particles from their nucleus Nuclear Equations - These show what happens when alpha, beta and gamma are emitted Background Radiation - You can't escape it, you are currently being irradiated Makes me really happy that the lesson fits with the needs of the moment! What is background radiation physics?

Thank you for this feedback and I'm really pleased to hear that you liked the lesson! So the opposite charges of protons and electrons balance each other, producing a zero net charge. the number of protons in the nucleus of an atom, the sum of the number of neutrons and protons in an atomic nucleus, they have identical numbers of protons and electrons.
