[en] The monograph is a small manual to get a knowledge of ionizing and non-ionizing radiations. The main chapters are: - Electromagnetic radiations - Ionizing and non-ionizing radiations - Non-ionizing electromagnetic radiations - Ionizing electromagnetic radiation - Other ionizing radiations - Ionizing radiation effects - The Nuclear Safety Conseil
[en] Full text: The radiation dosimetry program is an important element of operational radiation protection. Dosimetry data enable workers and radiation protection professionals to evaluate and control work practices to eliminate unnecessary exposure to ionizing radiation. The usefulness of the data produced however depends on its quality and traceability. The emphasis of the global dosimetry program is focused through the IAEA/WHO network of secondary standard dosimetry laboratories (SSDLs), which aims for the determination of SI quantities through proper traceable calibration of radiation protection equipment. The responsibility of SSDL-NUCLEAR MALAYSIA to guarantee a reliable dosimetry service, which is traceable to international standards, is elucidated. It acts as the basis for harmonized occupational radiation monitoring in Malaysia.
[en] The problem of the harmful effects of different radiations to which workers are more or less seriously exposed was studied as a whole. It is show that any ray without exception can cause damage to the ocular apparatus since even natural light, when suffered too intensely or for too long, can cause sight disorders and lesions, and this applied even more to so-called invisible rays: infrared, ultraviolet, laser. Powerful short-range radar waves and X, gamma and cosmic rays are also mentioned. This work covers both a physical study of the above radiations and a clinical anatomical study on the pathogenesis of the eye lesions they cause (more or less serious and more or less irreversible damage to the retina, cornea, crystalline lens, conjunctive tissue). General and individual protective measures are reported, and finally the work laws are discussed in terms of their application to radiation-induced eye troubles
[fr]On a etudie dans son ensemble le probleme des effets nocifs des divers rayonnements auxquels les travailleurs sont plus ou moins gravement soumis. On a montre qu'il n'est point de rayon qui ne puisse etre nuisible au niveau de l'appareil oculaire, puisque meme la lumiere naturelle, lorsque ses effets sont trop intenses ou trop prolonges, peut provoquer des troubles et des lesions de la vue; a fortiori, les rayons dits invisibles, infra-rouges, ultra-violets, le laser. On a cite egalement les ondes Radar a forte puissance et a faible distance, les rayons X, gamma et cosmiques. On a realise, a la fois l'etude physique de ces radiations, l'etude anatomo-clinique et pathogenique des lesions oculaires provoquees (atteintes plus ou moins serieuses, plus ou moins irreversibles, au niveau de la retine, de la cornee, du cristallin, de la conjonctive). On a expose les mesures de protection tant generales qu'individuelles et enfin la legislation du travail telle qu'elle peut etre appliquee aux atteintes de l'oeil par les rayonnements
[en] A brief introduction to the sources and units of radiation handled or used by men in laboratories and reactors is given. The distribution of radionuclides which enter the human body due to various causes and their elimination is described. The mechanism of radiation damages such as: (i) immdiate radiochemical effects (ii) biological effects (iii) the temporal stages of radiation action and (iv)GENETIC EFFECTS OF RADIATION-mutation as well as the principle of radiation protection are explained. An account of the various meters used such as monitors, dosimeters, etc. is given. Important precautions to be taken while handling radioactive substances are enumerated. (ΣB.)
[en] The Committee on Interagency Radiation Research and Policy Coordination (CIRRPC) was mandated in order to coordinate radiation matters between government agencies, evaluate radiation research, and furnish advice on the formulation of radiation policy. CIRRPC conducts some activities in the area of nonionizing radiation that comes from radio, television, microwaves, and radar emissions. However, most of CIRRPC's activities deal with the higher end of the spectrum. This radiation includes x-rays, gamma rays, and laser photons
[en] Justification of facilities and activities that give rise to radiation risks must yield an overall benefit. Human imaging using radiation for the detection of concealed objects that can be used for criminal acts that pose a national security threat shall be justified only by the government. Cases in Indonesia, the use of radiation examination for non-medical human imaging to fight against drug crime in the correctional institution needs to be justified. Drugs crime is regulated in Act No. 35 of 2009 whereas correctional institution is regulated in Act No. 12 of 1995. Justification process the use of Body Scanner for detection purposes in correctional institutions related to drug crimes in Indonesia will be the main focus. Discussion on drug crime in the correctional institution and the government’s effort to improve the detection and examination system in the correctional institutions using x-ray for non-medical human imaging. The results of National Survey in 2017 conducted by National Narcotics Board (BNN) Data and Information Research Center in collaboration with the Health Research Center University of Indonesia obtained the number of socio-economic cost losses due to drugs abuse in Indonesia during 2017 reached to eighty-four trillion Rupiah (around six billion and three hundred million Dollar US). The following is the prevalence of drug abusers in Indonesia in 2011, 2014, 2017, and 2019.
[en] Ionizing radiation is dangerous in two different ways: (i) high doses can cause serious injuries and (ii) low doses involve the risk of cancer and inheritable harm. The radiation protection aims at avoiding the high doses and keeping the low doses as low as possible. The estimation of the probability of radiation damage makes it possible to arrange radiation protection against each radiation source. In the case of ultraviolet radiation, similar assumptions are made. (G.B.)
