pawn Code:

public OnPlayerUpdate(playerid)
{
    if(IsPlayerInRangeOfPoint(playerid, Float:range, Float:x, Float:y, Float:z))
    {
        if(!GetPVarInt(playerid,"RadiationTimerWorking"))
        {
            LoseHP[playerid] = SetTimerEx("NegativeDown",1000,1,"i",playerid);
            SetPVarInt(playerid,"RadiationTimerWorking",1);
        }
    }
    else SetPVarInt(playerid,"RadiationTimerWorking",0);
    return 1;
}

This will prevent the timer from from bugging
