Apart from the major Nuclear Analytical Services, the LSD engages in many programs related to quality and safety assurance in health sector of the nation as well as environmental protection. In these endeavors the division mainly concentrates on the radiation monitoring and radiation protection aspects.

The division in collaboration with Central Environmental Authority engages in air pollution monitoring for identification of airborne particulate matter (APM) in major urban areas in the country. APM data set has been established for Colombo Fort, Orugodawatta areas and Kandy in which previous monitoring stations situated in. Current air quality monitoring station is established in Biyagama to study the air quality levels at an Industrial Zone.

In collaboration with Marine Environment Protection Authority (MEPA) of Sri Lanka, the division executes a program on radiation monitoring in marine and coastal environments. Also, we merge with the National Aquatic Resources Agency (NARA) for radioactivity monitoring in marine life forms, fish, sea water and sediments.

The division also provides services to health sector by testing the waste water from hospitals where cancer therapy is performed using radiotherapy. The gamma spectrometry laboratory engages in identifying mainly the Iodine-131 (I-131) radionuclide contamination in waste water samples received from hospitals through the National Water Supply and Drainage Board (NWSDB).

The division has initiated the national level important project on establishment of cyclotron facility for the production of radiopharmaceuticals needed for health care services, in collaboration with the International Atomic Energy Agency (IAEA) and the Ministry of Health.  The facility will be helpful to upgrade the health services, especially cancer patient care management in the country.  The objective of this project is to establish a fully operational cyclotron based radiopharmaceutical production facility to produce PET tracers (eg. 18F-FDG) needed for PET/CT scanning in the country. The IAEA has approved the same project (IAEA SRL 6037) under its technical cooperation assistance program to develop the human resources and quality control laboratories with respect to the cyclotron facility.
