About the fire in the Exclusion Zone

On April 27 at 07:30 a.m. two points of fire were partially localized at the areas amounted to 4,2 and 4,0 hectares. However, at 14.00 p.m. strong wind gusts caused a rapid spread of fire. Measures on ignition elimination in the exclusion zone are in progress. As of 18:00 April 29, the fire is localized. Rescuer workers from Chornobyl, Kyiv and Kyiv region and equipment belonging to the State Emergency Service of Ukraine are engaged in the operation.

According to the radiation control data, testing levels (determined for this area) by indices of radionuclides content in the air as well as exposure dose capacity are not increased.

Detailed information about radiation level in the exclusion zone for the period from 22nd till 28th of April can be found here.

The detailed information on radiation level on Chornobyl NPP site, dated April 29, 2015, is given below:

Sample date


Sampling site


137 Cs activityconcentration, Bq/m3 137 Cs acceptable concentration, Bq/m3
27.04.2015 Administration Building of Radiation and Process Monitoring Department 1,00×10-02  






27.04.2015 Interim Storage Facility – 2 3,20×10-02
27.04.2015 Personnel Facility – 2 3,20×10-02
28.04.2015 Sanitary Passage “Semikhody” 2,20×10-02
28.04.2015 Onshore Pump Station – 3 2,50×10-02

Thereby, the 137 Cs activity concentration (before and during the fire) has not changed and was considerably below the acceptable level of 137 Cs activity concentration in air for population, defined by Radiation Safety Standards of Ukraine (normative document НРБУ-97).

On April 29, 2015 radiation in the city of Kyiv remains unchanged at the value of 13 mR/h which is usual background radiation level for this area (in particular, radiation level in Bagrynova Gora is 13 mR/h, in Zhulyany – 13 mR/h and Hydropark – 9 mR/h ). Details – the link.
