AbstractAbstract
[en] This invention relates to a personal continuous air monitor capable of giving immediate warning of the presence of radioactivity. The monitor has a filter/detector head to be worn in the breathing zone of a user and it contains a filter mounted adjacent to radiation detectors, and a preamplifier. The filter/detector head is connected to a belt pack to be worn at the waist or on the back of a user. The belt pack contains a signal processor, batteries, a multichannel analyzer, a logic circuit, and an alarm. An air pump also is provided in the belt pack for pulling air through the filter/detector head by way of an air tube.d

AbstractAbstract
[en] The size and complexity of the CMS detector makes the Data Quality Monitoring (DQM) system very challenging. Given the high granularity of the CMS sub-detectors, several approaches and tools have been developed to monitor the detector performance closely. We describe here the History DQM, a tool allowing the detector performance monitoring over time.

AbstractAbstract
[en] This Good Practice Guide has been written by a working party of experts from the UK Ionising Radiation Metrology Forum. It describes procedures and methods for assessing radiation levels, outlines the thought processes needed to carry out the measurements and gives practical advice. The methods described are general and based on currently accepted good practice

AbstractAbstract
[en] The design is proposed of the electrical circuit of a radiation alarm device with acoustic indication proportional to the intensity of the radiation. The indication is set below the threshold of the alarm signal value. The advantage of the designed circuit is the supply of acoustic information provided for estimating radiation intensity which in its acoustic effect is independent of the set threshold signal value.

AbstractAbstract
[en] Nowadays, with the growth of technology, many devices and equipment's can be connected to the network and internet to enable online data acquisition. Centralized radiation monitoring system utilizes a Local Area Network (LAN) as a communication media for data acquisition of the area radiation levels from radiation detectors in Malaysian Nuclear Agency (Nuclear Malaysia). The development of the system involves device configuration, wiring, network and hardware installation, software and web development. This paper describes the software development on the system server that is responsible to acquire and record the area radiation readings from the detectors. Then the recorded readings are called in a web programming to be displayed on a web site. The readings with the time stamp are stored in the system database for query. Besides acquiring the area radiation levels in Nuclear Malaysia centrally, additional features such as data conversion from mR to μSv and line chart display are developed in the software for effective radiation level trend observation and studies.

AbstractAbstract
[en] A brief review of the status of instrumentation for monitoring environmental pollutants is given. Pollutants are divided into six broad categories: trace elements, pesticides and herbicides, ionizing radiation and radionuclides, asbestos and other microparticulates, and gaseous pollutants. (U.S.)

AbstractAbstract
[en] Normally, these vehicles are used to reinforce the atmospheric supervision network based on four fixed stations. In the case of a planned atmospheric discharge they have to control contamination levels and check that these conform to the scattering forecasts. In the case of accidental atmospheric pollution, their role is to rapidly demarcate the pollution zones and to follow the evolution of this pollution. The main measurements carried out are: - Detection of ambient gamma radiation from 10 μrad/hr to 1000 rad/hr. - Detection of the alpha and gamma contamination. - Detection of the beta and gamma contamination of the ground.

En temps normal, ces vehicules ont pour but de completer le reseau de surveillance atmospherique qui s'appuie sur quatre stations fixes. En cas de rejet atmospherique concerte, ils doivent controler les niveaux de contamination et verifier qu'ils sont conformes aux previsions de diffusion. En cas de rejet atmospherique accidentel, ils ont pour mission de delimiter rapidement les zones de pollution et tenir a jour leur evolution. Les principales mesures effectuees sont: - Detection des gamma ambiants de lO μrad/h a 1000 rad/h. - Detection de la contamination atmospherique en alpha et beta. - Detection de la contamination du sol en beta et gamma.

AbstractAbstract
[en] The new German Radiation Protection Ordinance, which entered into force on April 01, 1977, indicates limits for protective measures to be taken in cases of surface contamination at work stations and of objects, which are very low. In addition, it is provided that persons working in areas containing unsealed radioactive sources be examined for contamination of the skin and clothes. Such checks are to be made as soon as these persons leave the areas referred to above. The imits stated for the skin are even lower than those quoted for the clothes outside controlled plant areas. Accordingly, the question arises in many cases whether the detectors used so far, or to be newly purchased, are capable of detecting surface contamination ot the order of, or even below, these limits. This contribution is to help in assessing contamination detectors with respect to their lower limits of detection. (orig.)

Die am 1.4.77 in Kraft getretene neue Strahlenschutzverordnung (StrlSchV) gibt in Anlage IX zu den Paragraphen 35 und 64 'Grenzwerte fuer Schutzmassnahmen bei Oberflaechenkontamination von Arbeitsplaetzen und Gegenstaenden' an, die sehr niedrig sind. In Paragraph 64 (2) wird darueber hinaus gefordert: 'An Personen, die Kontrollbereiche verlassen, in denen offene radioaktive Stoffe vorhanden sind, ist zu pruefen, ob die Haut oder die Kleidung kontaminiert ist'. Diese Forderung wird man sicher so zu verstehen haben, dass bezueglich der Haut noch niedrigere Grenzwerte gelten als die in Anlage IX fuer Kleidung ausserhalb betrieblicher Ueberwachungsbereiche genannten. In vielen Faellen ensteht daher die Frage, ob die bisher verwendeten oder neu anzuschaffenden Messgeraete in der Lage sind, Oberflaechenkontaminationen nachzuweisen, deren Wert in der Groesse dieser Grenzwerte oder darunter liegt. Dieser Beitrag soll dazu dienen, die Beurteilung von Kontaminationsmessgeraeten im Hinblick auf ihre untere Nachweisgrenze zu erleichtern. Es werden Kriterien sowohl fuer Geraete zur Messung der Kontamination am Arbeitsplatz gemaess StrlSchV Paragraph 64 (1) als auch fuer Geraete zur Kontaminationspruefung am Kontrollbereichsausgang gemaess Paragraph 64 (2) angegeben.
