Technical Support & Radiation Protection Department

About Department

TAEC established the section of technical support and radiation protection section to enhance regulatory activities in controlling radiation contamination in environment, foodstuff and fertilizer for the purpose of protecting the people and the environment from harmful effects of radiation. Various nuclear weapons tests and the historical radioactivity fallout from Chernobyl power plant accident in 1986, Fukushima Daichii in 2011 and many other tests currently going on, enforce the Commission to enforce in Laboratory performance and ensure most of its services are accredited by 2025.

Roles of Technical Services and Radiation Protection Department

·    Perform measurements of radioactivity analysis in foodstuff and environment;

·    Perform radioactivity measurements analysis in human body;

·   perform measurements of elemental composition in various samples;

·   carry out environmental radiological impact assessment in facilities and during nuclear and radiological emergencies;

·    provide repair, maintenance and ensure quality of medical and related nuclear scientific equipment;

·   provide personnel dosimetry services and workplace radiation monitoring, and radiation safety analysis services to ionizing radiation practices;

Nuclear Instrumentation Maintenance Laboratory

NIM has well equipped laboratory whose main objective is to provide countrywide co-ordinated services, training in quality control, repair and maintenance of nuclear instruments and nuclear related equipment.

Fixing X-ray machine

Repair of nuclear density

Repair of CT scan

Repair of Gamma

Repair of Mobile x-ray

Repair of C-Arm

The long term objective of the NIM laboratory is to strengthen the national capability in nuclear instrumentation maintenance. Some of the major services offered include:

  • Installation, repair and maintenance of nuclear instruments, scientific instruments, as well as nuclear- related equipment used in research, industry and medicine such as x-ray machines, gamma cameras , CT scan, ultrasound, various radiation monitors and detectors.
  • Calibration and Maintenance of Nuclear Density Gauges such as Troxler and Humboldt.
  • Design and fabrication of low-cost electronics gadgets for local application.
  • Conduct training in the field of nuclear instrumentation for local biomedical engineers, technicians and scientists.
  • Consultancy services and service contracts for scientific instruments, biomedical and electronic equipments.
  • Host students from various universities and train them in the field of nuclear instrumentation during their fieldwork.

Personal Monitoring Laboratory

Occupational exposure from external exposure of radionuclides can occur as a result of various activities.  These include work associated with the different stages of the nuclear fuel cycle; the use of radioactive sources in medicine, scientific research, agriculture and industry; and occupations which involve enhanced concentrations of naturally occurring radionuclides.

The individual Monitoring of Occupational Exposed Workers (OEW) in Tanzania Started in 1986 and about 2000 workers are covered by this service up to date. The service is a legal requirement and forms part of the license conditions.


  1. Demonstration of good working practices which indicate the adequacy of supervision, training and engineering standards where the results of individual monitoring can be used to give information about conditions in the workplace and thus provide a means of establishing whether these are under satisfactory control and whether operational changes have improved or worsened the radiological working conditions,
  2. Estimation of the actual radiation exposure of workers, to demonstrate compliance with legal requirements,
  3. Evaluation and development of operating procedures by means of collected data both for individuals and groups where individual monitoring data may be used to identify both good and bad features of operating procedures and design characteristics, and thereby contribute to the development of safer radiation working practices,
  4. Provision of information which can be used to assist workers in preventing exposure and motivate workers to reduce their exposure,
  5. Provision of information for the evaluation of dose in the event of accidental exposures.

Dose rate data may be used for:

  1. Risk benefit analysis,
  2. Medical records and epidemiological studies of the exposed population.
  3. Ambient radioactivity monitoring in the URT


The National Calibration Laboratory for the units Gray (Gy), sievert (Sv) and Becquerel (Bq).

The History Of SSDL

TAEC has established a National Standard Dosimetry Calibration Laboratory (NCL) for ionizing radiation in 1991. And Years Later became the member of IAEA/WHO SSDL Network. The Neighboring countries have shown the close cooperation such as Uganda, Kenya, Rwanda, Burundi, Malawi, Zambia and DRC Congo.

Our services

SSDL Offers the calibration of dosimeters for ionizing radiation measurements in addition to issuing calibration certificates for the following:      


Survey Meters and Participating in

Co-60 beam therapy level Intercomparing
X- Rays
Radiation Survey Meters
Radiation Protection
Handheld monitors and personal dosimeters 

SSDL’S radiation Beams for Calibration

1.      X- ray Unit 40 -225 kV

2.      Sources Cs-137 and Co -60 for radiation protection.

Competence at International Level

The National Calibration Laboratory is an active member of International Atomic Energy commission which is traceable to BIPM (The International Bureau of Weights and Measures)
