Abstract Sound pollution has been a major challenge in both the developed and the developing nations and demand serious attention to check the health hazards, just as is the case of radiation studies. The effort is a drift from the urban noise to the rural oil and gas producing communities of Nigeria, taking Oil Mining Lease II as a case study. The communities cover Ebukuna, Ama- Ubulom, Amajob, Ama-Ngerenkpon, Agbalama, Otako, Okoloile, Ama-Friday, Otu-Ogon and Ngo town, in the other of 1 to 10 respectively. The communities have a noise range of 44.49dBA to 63.60dBA, with Ebukuna ranking highest and Otako lowest. This is indicative that the Oil and Gas industrial activities do not have adverse noise effect from delivery pipes. The participatory investigation shows severity from oil spills, which has left the creeks barren and caused migration of the citizenry across the shores of Nigeria and West Africa for green fishing. A complementary research results of the radionuclide contents of 40k (Bq/l), 235Ra(Bq/L)m show the values twice above the recommended standard by WHO in table 2, which is indicative of the Oil spill impact in the region and transport from Ogoni spill down to Andoni (Obolo) as the ultimate sink. The UNSCEAR of the bottom sediment is even much higher
Keywords Radiation, Sound Pollution
Andoni (Obolo) is one of the 774 local government areas of Nigeria and among the 23 local government areas of Rivers State.
It is located on 70 181E and 70 331E of Greenwich meridian but transverse laterally by latitude 40 311N. it is bounded by the Ogonis in the North, Bonny to the West, Imo River/Opobo /Ikot Abasi to the East and the Atlantic Ocean to the South. It has seven multinational firms on its land and offshore, namely;
AMNI, International Petroleum Development Company (Ngo field)
Chevron Tubu field Development OML 52
Elf Petroleum Nigeria Limited OML (100)
NNPC Joint Venture, Offshore Operations OML 99, OML 101, OML 102 with Production capacity of 500 million barrels of oil
Mobil Oil Fields Eastern Obolo and Ibeno Ethnic brothers.
Shell Petroleum Development Company of Nigeria Otakukpo field
The Green energy International Limited and Lek Oil Collaboration on OML II and OML 52. A lot of competitive study has been done on sound pollution impact.
These include  .
The study show both the impact of noise and radiological hazard index for most communities as above the WHO standards and need a good environmental health educators to enlighten the people and government
The methods involves the use of a CEL 231 and CEL 254 Digilert 100 and radalert 200, geographical positioning system (GSP) and a participatory tool box for forensic investigation of Oil and Gas exploitation impact.
The result and analysis are as shown in table 1: Baseline flow station noise level of facilities while figures 1 – 4 tells us specific noise details at the surveyed point
At the close; table 2 gives us summary of the radiation index in water while fig 5 show us the contour of the spread, fig 6 at the summary is indicative of the average noise level for the 10 sampled communities, which is minimal.

Figure1. Noise level of Ebukuma Community in Andoni L.G.A
From the above chart, we see that:
The residents of Jetty village are exposed to the most noise (74.30dBA) in this community.
Those living around Hospital are least affected (44.20dBA) by the noise in the community.
Figure 2. Noise Level of Ama-Ubulom Community in Andoni L.G.A
From the above chart, we see that:
-The residents of Bike Union House are exposed to the most noise (65.80 dBA) in this community.
-Those living around Stream Water Boundary are least affected (44.20 dBA) by the noise in the community.
From the above chart, we see that:
Figure3. Noise level of Agbalama Community in Andoni L.G.A
-The villagers staying around Town Square are exposed to the most noise (68.70 dBA) in this community.
-Those living around Bere Compound are least affected (44.60 dBA) by the noise in the community.
Figure4. Noiselevel of Otako Community in Andoni L.G.A
From the above chart, we see that:
-The villagers staying around the Entrance Boundary are exposed to the most noise (62.40 dBA) in this community.
-Those living around the Anglican Church and Fah Edeh are least affected (42.40 dBA) by the noise in the community.
Table2. Radiation hazard indices in sea water
ELCR x 10-3
From table 2 which shows the average Radiation Hazard Indices in Sea Water it is established that the index is above world health organization by twice the value and needs more caution as to the source and the impact on the fishing community which is a major discovery.
Figure5. Contour mapping of Ama-Friday, Otu-Ogoon, Ngo and Ebukuma Communities
The figure 5 shows the distribution of the Radiation Hazard Indices in Sea Water among the riverine community of the surveyed field.
SUMMARY AND RECOMMENDATION
Figure6. Average noise level for all Communities showing minimal impact
Sound pollution and radiation impact survey of OML II was carried out. The findings shown in figure 1-4 is indicative that industrial noise impact from network of oil and gas pipeline is negligible but could escalate for flow stations on full production process. Reference table 1.
The radio nucleic activity concentration in the water of the study area is very high, reference Table 2. This is traceable to the heavy drill work in the area, oil spillages and drift oil and gas pollutant from the Ogoni leakages and remediation work in Ogoni which is North of Andoni, the study area. The recommendation is for an integrated environmental evaluation, remediation and rehabilitation of the people on aqua cultural alternatives to boost fish production.
