Radiation Monitoring (hendriyanto haditjahyono) ICTP IAEA BATAN - PowerPoint PPT Presentation

Radiation Monitoring (hendriyanto haditjahyono) ICTP – IAEA – BATAN Workshop on Wireless Sensor Networks for Radiation Monitoring Jakarta, 1 ~ 5 October 2012

Outline: Introduction Ionizing radiation Radiation monitoring activities and instruments Hardware of radiation monitor Radiation Monitoring page 2

Objectives: After following this session you will be able to distinguish between radiation and ionizing radiation; list various type of radiation source; describe the radiation dose concept; describe the purpose of radiation monitoring activities; mention various type of radiation monitoring instruments; explain the hardware of radiation monitor. Radiation Monitoring page 3

Intoduction Nuclear technology nowadays is applied in many areas, from medical to industrial, from agricultural to electrical. Radiation Monitoring page 4

Intoduction Every nuclear facility potentially emits a certain level of radiation to its surroundings. The public must be aware of that radiation responsibility to monitor radiations Radiation Monitoring page 5

Ionizing Radiation Electromagnetic Waves is not detectable by human sense can penetrate any material Radiation Monitoring page 6

Ionizing Radiation Radiation Sources: Radioactive material Natural and Artificial Interaction of energetic particle Fission reaction Radiation Monitoring page 7

Ionizing Radiation Radiation Dose a measure of the energy deposited by radiation in a target. (Rem or Sievert) Dose rate Radiation dose per unit time. (Rem/hour or Sievert/hour) Radiation Monitoring page 8

Ionizing Radiation Radioactive Contamination Radioactive substances on surfaces, or within solids, liquids or gases, where their presence is unintended or undesirable. Radiation Monitoring page 9

Radiation Monitoring Activity By definition (IAEA Safety Glossary – 2007) Radiation monitoring involves the measurement of radiation dose or radionuclide contamination for reasons related to the assessment or control of exposure to radiation or radioactive substances, and the interpretation of the results. Radiation Monitoring page 10

Radiation Monitoring Activity Purpose of monitoring Routine Task related Special Target monitoring: individual (personal) Workplace (area) Source environment Radiation Monitoring page 11

Radiation Monitoring Activity Instruments Radiation monitoring activities can be carried out manually as well as automatically, all day long, without any human intervention. Radiation Monitoring page 12

Radiation Monitoring Activity Calibration Bequerel radiation/ counts/ sievert/ or Currie second second hour (energy) Radiation Monitoring page 13

Hardware Main Block of Radiation Monitor Radiatio n signal processing HID detector HV Ext Radiation Monitoring page 14

Hardware Detector: To convert the nuclear energy become electric signal. The number of electric pulses is proportional with the incoming radiations The pulse height proportional to the radiation energy. HV: To polarize the detector (anode and cathode). Signal Processing: To shape and amplify the electric signal Radiation Monitoring page 15

Hardware Arduino module Radiation Monitor hardware and software Radiation Monitoring page 16

Tiank You & good luck ... !
