History
In Iran, environmental radiation monitoring began in 1976 by measuring the concentrations of some radionuclides in air, water, soil and food samples in Bushehr and Isfahan provinces. The results of these measurements represent the normal levels.
After the Chernobyl accident main activities focused on environmental radiation measurement, including artificial radionuclides such as 137Cs in soil and food samples .

II. Environmental Radiation and Radioactivity Monitoring in Iran 1. Monitoring Plan
The purpose of a background radiation monitoring program is to evaluate the normal levels of radionuclides and radiation in the environment from natural sources and atmospheric fallout and to monitor trends over time
This program also addresses general aspects of monitoring for
long lived radionuclides widely dispersed in the environment
following a radiation accident, or as residual waste from past
practices.
This includes monitoring of the content of natural and human
made radionuclides in foodstuffs and drinking water.
The types of media routinely sampled in this program include
milk, food stuffs, air, water, soil, sediment, flora and fauna.

Control the levels of radioactivity in Foodstuffs
A national system for monitoring and controls the levels of radioactivity in foodstuffs and selected commodities have been established by INRA.
Control the levels of radioactivity in Foodstuffs (cont.)
INRA has prepared a document for controlling the level of radioactivity in
foodstuff (Doc. No. INRA-RP-WI-200-70/38-0-1388).
In this document, the radionuclides action levels for foods have been determined.
In the case of nuclear accident or radiological events that might affect the country
and in the post emergency situation , Derived Intervention Levels (DILs) has been
determined base on a generic intervention exemption level of around 1 mSv in a
year and can be used to prevent or reduce exposure due to consumption of
foodstuffs.
The kinds of foodstuff samples, radionuclide targets, analysis, sampling frequency
and sampling points are mentioned in the document and base on this foodstuff
monitoring programme, INRA has controlled the levels of radioactivity in
foodstuffs.
Control the levels of radioactivity in Foodstuffs (cont.)
Some imported foods, some local foodstuffs; including fish and dates, water, vegetables, fruits, rice, corns, meat and milk are monitored regularly with gamma spectrometry and alpha spectrometry.
Food basket: consumption of locally produced food or purchasing the food products from general distribution system
INRA however, provides technical services on request from exporters to carry out radioactivity measurements and issues certificates of radioactivity levels in food stuff for export purposes.
Control the levels of radioactivity in Foodstuffs (cont.)
There is a national Standard for Water (St. No 1053) on the quality of water intended
for people consumption in IRAN. This standard deals with the microbiological,
chemical and also radioactive aspects. As far as the last point is concerned, the
technical procedures specifying the analyses to be carried out as well as the
Directive’s modalities of application have been prepared.
This national Standard for Water (St. No 1053) has prepared base on “Guidelines for
Drinking- water Quality, second ADDENDUM TO THIRD EDITION,Volume1,
Recommendations, World Health Organization; WHO, Chapter 9; Radiological aspects
(2006)”
A reference effective dose of 0.1mSv from 1 year’s consumption of drinking-water
(which is 10% of the intervention exemption level recommended by the ICRP for
prolonged exposure situations (ICRP 82)

• After Fukushima accident Cs-137 or other radionuclides were not detected in imported foodstuff in Iran.
